Get the balance right.
One of the trickiest parts of growing cannabis is striking the right balance of nutrients in your plants. Even then, having the right nutrients present in your medium doesn't guarantee proper uptake by the plant.
In this comprehensive tutorial, Ganjier Director Derek Gilman and Simon Hart of Grotek Nutrients discuss how to identify nutrient deficiency problems in your garden early and accurately before major damage sets in, covering both the vegetative and flowering cycles, and the unique considerations for each.
Wish I had these types of videos when I started 20 years ago, these youngsters have it easy these days.
This is pure bad info from a poser level grower. Another regurgitator. Starts off with the classic Ag line about calcium availability, even though Cannabis hyper accumulates cannabis..
The CalMag generation is doomed. It's a bunch of clones spewing bad info the entire time their mouths are open.
What do you mean these kids have it easy? apart from the fact that its still highly illegal to grow it or posses it in most countries and in some you can even get the death penalty cannabis growers only have it slightly easy in the US and Canada its still only decriminalized in the Netherlands nobody has it easy when it comes to cannabis the government still continues there so called war on "drugs"
@@zhayward3190 Haha jeepers dude YTJ was commenting on the amount of free & accessible good information there is about growing, not the legality of it.
Yessir starting my first six plant in a bathroom with a heater and an open window for air flow and its going well, going to bring them outside when it gets better
@@sheddy22 i hope ur plants survived and yeilded very well ma good man
Since I switched to living soil a year ago, I've had no problems .
Haven't even re amended yet. All I do is mulch the leaf.
If I continue to have people walk up to me and ask me questions about how to grow, I will need this Gangier course as soon as possible. I have been saving since last year when I discovered this channel. I have learned so so much from this group of fine people, that my first grow last year was extremely abundant and very very good medicine. Big shout out to Derek, for being cooler than the other side of the pillow. Thanks again!
thats why i grow with organic ingredients never had any problems.
No matter what you grow with the ph has to be perfect! In veg they can handle 5.8 - 7.3 ph but during flower they absolutely have to be beetween 6.2 and 6.8 ph. It's best to always be in the 6.2 to 6.8 ph! 6.5 is pretty much perfect ph! :)
Literally facts Lmaooo these salt growers will never get it
Organic grower and never check ph. Using the cleanest water possible and the healthiest soil I can come up with and I’ve never seen healthier plants!
@@michaelc840 I've done many combos and organic dry amendments aren't on the top of my list, just saying..Their arrright..
@@GoldenBoy-et6of with organic growing, ive heard about and done watering without ph-ing it. It seems to be working fine for me, that's one of the reason why I switched to organic growing.
Amazing video. This guest spoke facts and , not marketing... His answer was on point, not what most wanted to hear. Most want an answer of a product to buy, and not a technique to develop.
Great again!!!!!!!
Facts!!!!!!!!!
Been growing sense 1974 this video is 5star thank you Simon for all the great info all growers should watch this simple approach

@@jameshecht3471 There's a litany of grammar mistakes too, I doubt he cares lol
So, before watching this, I saw a "deficiency", wanted to address with a quick nute soak, decided to wait it out based on the advice here. My problem was a slight over watering problem. Letting it get dryer than I was more comfortable with before watering again yielded incredible results. While, I didn't think I was over-watering, I was, Newbie mistake!
hows it going man? update? :D
I had the opposite going on with one, got too dry and hot and locked out!! Basically hitting the eject button too early on that one, sadly. Lessons learned, now back to the EarthBound ones in the greenhouse. They look awesome, 8-footers already... around!😎👍👌
When the leaves are still nice and perky, but the pot is light...really light weight. That's when you water again. If you go too far in between waterings, you'll get the leaves drooping. That's when you've gone too far and most likely affected root hairs vs root shafts. Shafts absorb water, hairs absorb nutrients. When root hairs die, only root shafts remain, hence why growers can easily over water. It's not nutrient lock out, it's the death of the root hairs. I feed once every 3 waterings. I hardly ever get deficiencies. Good luck ✌👍
Makes a lot of sense
Ahh new upload lovely. Good growth and vibes to yall gardens this year.
Living soil, organic nutes, and pH your water/nutes.
Well spoken! I love a good lecture, but also love the "coffee chat" style conversation
Great video. First time grower and it’s been a journey these last few months. Saving this video 😂😂😂.
This channel deserves way more subs
Gracias Derek tu programa es de gran ayuda para aprender 🙏🍀💚
When I moved to my current house, I had no idea that my well water was going to be such a major issue. I have a filter on my main to remove sediment. Outdoor plants were fine, but as I used the water on my container plants, I noticed deficiencies. I tested my water as little as an hour after correcting the pH, it was creeping back up. By the next day it was 9.4! My tds meter was not accurate and what I discovered after having the water tested was that I had an extremely high level of dissolved carbonate. The filter will not remove the dissolved solids so I installed an RO filter system for my indoor plants and the water comes out at 6.4. Add a little food and it is right between 5.5 - 6, I don't even need to correct it at all. But for months I could not figure out what was going on and it was extremely frustrating.
Yeah my well water is around ph 8 but when it goes through my salt system (or resin idk) its somewhere in the sixes.. I have a bypass for outside so I dont use my "filtered" water but when watering in pots, it creates deficencies. I correct that by adding a bit of sulfur to my soil.
I don't think I ever heard a major grower mention the problems they usually run into. That was informative. As I put a pinch of epsome in my water.
I've learned so much from watching thanks for sharing
Brilliant! Thanks for your work and love for the plant!
I grow 12 different strains at once so i deal with deficiencies all the time. The struggle is real
I thought 6 was hard, I don't Even wanna think of 12. Damn, u must have been running water all day
@dmo848 i kept having too many problems so I cut back to 4 strains
I have a tiny 2.5x2.5x6' tent. I learned quick when to feed and how much. I use the Humboldts Secret A/B bundle at 1/3 dose , a little CalMag then Ph to 6.5. Works out great too.. Less is more 😎
This is gold, thank you for these tips!
Thanks d so much information man love this channel respect n love from the UK ❤🎉😊
Hi i love this channel , iam french grower since 24 years olds but in my country is 100% illégal (moving to humboldt is my dream) .
To cover your deficiencies in micronutrients mineral magic of GHE is perfect besides bringing a lot of bioavailable silicate to your plants (which considerably strengthens their structures) it also contains magnesium, calcium, sulfur and iron in well thought out proportions.
To add.. root rot is very common with beginner home growers and they think it's a deficiency so they keep adding and adding and adding. Trust me root rot is probally the single worst thing and most common amongst beginner growers besides the usual bug problems.
I just learned so much, thank you. I do have a question though how often should one be watering?
When the top inch and a half has dried thoroughly, generally speaking
@@seekerfloyd7346 I went and got one of those meters to measure the moisture, and I generally will water when it is on the drier side of moist, but that is like 4 inches down. I am growing in tents in my house. It’s just confusing for me as for some reason my babies aren’t doing as good as they did last year. arghhhhh.
Depends on alot of factors. Rh, temperature, ect. I use the pick up the container method. If its heavy its got plenty of water
@@me-mj5dt I grow in 7 gallon pots, buried in the soil, I cant bother the roots by lifting them, I live in a desert
@@seekerfloyd7346 another way is just to look at them. I grow desert as well. Nice size containers. They should hold water pretty good. Its ok for them to get a little dry in my opinion. If you water and the plants puts out a strong odor that means its saying thank you. I needed that
Gilman can you do a quick video on molasses for plants and when is the best time to integrate into your feeding routine? I know molasses is a controversial product for some growers, some use it, some do not. Mahalos from Hawaii 🤙🏾🤙🏾 growmies
Great show. Thanks for the little nuggets off gold ✨. David
Thanks Simon! Derek, you are cool as shit bro! I wish I had you around in person to help keep me chill, your voice and demeanor is so calm and soothing. I bet you can get anything you want with your personality. Keep up the good work, wish you continued blessings!
I am using polyculture this year outdoor no feeding and plants are growing fastest in seven years no till soil 🌞
Thanks guys I think I have a magnesium problem
cannabis goes through 4 stages derek. seedling, sapling, vegetative, flower.
Some of mine have been through seedling, sapling, veg, flower, veg, flower, and are now back in veg for a third run.
Can't argue that fact. I run my seedlings and veg in the same RH room. Just feed them different. Do you find that using a different RH room for seedling make much difference? Curious. I'm only running 2 rooms right now
@@YouTubalcaine i ve done 5 reveg of the same plant. It got smaller buds after the 3rd reveg and less tricone production. I hated to loose that strain but there not ment to live that long. Was fun while it lasted
@@me-mj5dt I'll typically germinate or plant the sprouts right in their final pots and start normal feeding as soon as the cotyledons begin to die back. This way I avoid hardening stress and transplant shock entirely. Some hardship is good for 'em, but if you're doing long runs all those traumas add up and the hormonal chaos of being "reborn" will be tough enough as it is. Indoor flower and veg I do in the same tent, so after harvest all I need to do is flip the lights back to start the next cycle. If I'm doing a manifold (which I need for a strong base) I'll start in the nursery under T5s because you can get really dense node spacing without worry of overheating, but for humidity control it's only rooting clones that need special attention. Everything else I let adapt to their permanent habitats from jump street and then disturb them as little as possible. The truth is I'm not really growing plants. Mother Nature does most of the work, I'm just the concierge fetching water and trying not to monkey things up.
@@me-mj5dt y didn't u clone them?
Thx for a great video here. Could u do a video on if there are nutrient requirements for different cultivars?
Good stuff CHEERS ☝🏻💚🌱🌿🌳
Check ur soil ph b-4 you plant in the soil. If the soil ph is off, the nutes will lock out or will be less effective. With super "hot" soils, they will be acidic.
Or grow in living soil and never concern yourself with pH, EC, or PPM ever again…..
This is good advice you can also start with a supersoil blend and add a good general purpose dry fertilizer.
I like fox farm ocean forest with down to earth 444. Super easy grow... I don't check shit plants grow flawless
@@WestSide-hl1dl living soil still has to be ph controlled. The water needs to be ph controlled to or it change the ph too! I have an actual farm not for cannabis and my soil is super nutrient rich and dark amazing soil but I have to change ph of the soil for whatever crops I'm growing! Blueberries need 5.5ph while bananas need 7.5+ ph. Living soil doesn't automatically support all forms of life. Theres acid loving plants, neutral loving plants (cannabis) and alkaline loving plants which are mostly tropicals! 99% of all species are acid loving species because 99% of the worlds living soil is super acidic. Ph is the litteril most important thing as a gardener. Melons and pumpkin will only grow in alkaline conditions in a super tight ph range making them one of the hardest to grow plants because their ph requirements!
@@WestSide-hl1dl also ppm isnt a problem unless you use synthetic nutes! I dont use any nutes just organic stuff like worm castings and mulch and compost but I still have to ajust my soil ph all the time on my farm with calcite lime or dolomite lime depending on if I need the ph to change quickly I'll use calcitic or If I'm preparing the beds during winter for spring ill use dolomite which takes like 6 months to affect ph while calcitic takes like a week to affect ph!
learned from this that's why I do the lift container method Ang top inch method before water
stop doing that, use cover crops
if you can poke your finger into the top soil, you plant doesnt have a proper root system and cannot uptake anything
Organic living soil is king 👑
this dude look 45 but also looks 25 and for some reason looks familiar like from lord of the rigs or something.
🤣🤣🤣
i kind of look at it as three stages,, roots veg and flower.. to me roots are the most important... just me i guess...
There's quite a few stages but yea simplify it for people, preflower stage ,reveg I another stage from flowering back to a healthy vegging plant
Root zone temperature too.
Thanks for the help ✔️
i grow with livin soil organic and its the best chioce i made
I've heard that leaf curl downwards is a notifier to nutrient toxicity, and leaf curl upwards is because of irregular watering.. is this theory consistent with patterns y'all have observed?
Interesting
Very helpful
Great video lots of knowledge
Can you make a video of getting ride or spider mites and other bugs with natural or organic spray or liquid
Mosquito bits is a tested proven ingredient, soak in warm water then feed plant.
Agreed, how bout fungal , septoria leaf spot, us forest growmies, so far so good with H2o2 spray , halted it so far

Good plant symptom descriptions and tips, you could see Derek clench his jaw a little when talking about salts and the problems w over feeding 😂 I thought Derek was organic only🤷♂️
If you want legit yields organic in a soil medium is NOT the way to go, you get a plateau with that combo. I'm talking indoor home grower not commercial..
I believe epsom salt is a naturally occurring compound and can therefore be used in organic gardening.
Root bound could also be the problem & not the nutrients or water at all! It can happen in the ground but most of the time would be a plant in a pot.
rootbound is a myth
my baby seedlings are only on their 4th node and already have yellowing bottom leaves due to a lack of nitrogen and are planted in coco husk!
Can you tell me what're the amounts of Epson Salts (sulfate of magnesiun) per liter of water...? And is it better to do't foliar or in the soil...???!!!
Both are very effective, you wanna mist the underside of the leaves for foliar and the rate is 5ml per gallon, I do 2ml for half gallon. You want pure epsom, not fragranced, menthol etc..
Remember lights off if you foliar😂
bury a fish under each plant put it directly into the groud have a little fish pond and all that fish poop n fish water i water more towards the middle of the bed to make all the roots chase it
Bad watering, specially over watering causes a bunch of deficiencies, that in reality are not deficiencies due to nutrients not being, but rather due to root health....
Over complicating something that comes from nature will always have issues.keep it simple, organic & you'll be ok...keep it green,greens the go.too many chemical,s,salts block up the roots.
I ph my soil and don’t bother with the ph of my water. Works just fine for me. It’s the only way I will ever do it
Why do I have perpl leave s
What could be causing taco leaf and new top growth to be light green?
Heat. Light green is normal. Too much heat causes taco leaf. I hate that. Shade cloth or get it cooled down
It’s really not difficult to mix your own nutrients, it can be much cheaper and more effective. Never seen this “lockout” happen.
How many runs have you add? If more than 10 I'm VERY impressed you never had any issues with leaves?
@@stangcobra592 who smokes leaves???? typical internet grower bs
@@ohhi5237lol,spot on,need iron throw rusty nails in a bucket o water let stand a week and u got iron,need calcium add a drop of milk to ur feed,need phosphorus add bonemeal,need potassium add a bannana skin, if u know u know.
A storm took out my best plant last night. Five weeks away.
Great video. Do I need to measure the soil ph?
i got my butt kicked by my plants this year with nutrient issues... I will be flushing this week..
Magnesium defs show up weeks after the deficiency occurs.
This guy runs a nute company, grotek to name it. Mostly liquid mineral fertilizer. Of course he makes it sound super difficult. It’s not. One should start with growing the soil. Healthy soil equals healthy plants. Once that’s established growing healthy plants is easy. Especially true in a homegrown environment.
It’s all about microbiome, my Grammy, my mama, they were all about building soil first, the greatest abundance of year round veg and flowers, I harvested 9 lbs of flower off of 4 plants last year, I was stoked!! Happy grow y’all
Yup, all you need is one NPK ratio the entire grow, this multi bottle programs are a marketing scheme to sell you a lot of products. If you look for example how pros grow hydro tomatoes (rockwool), they use the same formula from veg to flower/fruit. There is really only one rule you have to care about with nutes if you're going salt/hydro - Calcium sources (mostly Calcium Nitrate or Calcium-ammonium Nitrate) has to be kept in a separate bottle/tank before you put in a solution. Calcium reacts with Sulphates (which is mostly epsom salt) and Phosphates (monopotassium phosphate). Other that that just keep your N-P-K-Ca-Mg-S ratio like 5-1-7-4-1,5-2 and you're golden. Plants don't need much P in flower it's a myth. 30ppm is enough..
thanx good video ...i came to conclusion that not feedingsome medium, but SOIL is everything ...even if you not have right light and perfect conditions ....good soil takes even bad ph, high temperatures ....bad soil and all prefect conditions will not give top results .....but im amateour thats my observation and conclusion .....and weed always grows better where it can STRECH roots in all directions from day one ...this poting and transplanting f..k uproot system and many deficiency is because of bad root spread and development ....my outsider plants stems is twice ticker than insiders ....but insiders buds is better quality because its not 36 C for 10 days ina roll like outsiders
Epson salts will help unlock many lockout issues.
Collecting data is the only way to correct a mistake.
So what you’re TRYING to say is that cannabis plants can’t grow in 7.5 or 5.5? So RAIN WATER IS 6.2 -6.5 or?
I feed my plants the same way all the way thru start to finish 1.4 to 1.7 ec with no problems im just a home grower so I'm not on a time limit since I started feeding the same all the way thru ive had no problems
So there really is no such thing as "overwatering". What you're doing is not letting your roots breathe by watering too often. If "overwatering" was true then Hydroponics and DWC wouldn't be possible as the roots sit in the water the duration of its lifetime
Overwatering in soil refers to the lack of oxygen available because it's saturated with too much water and the microbes/roots can't breathe
@@carrottoponcrak Correct. I was mainly stating that it's the roots not being able to breathe is the main culprit, not the water. As long as you have good drainage you should be 👍🏿
@@izzem even with drainage in a fabric pot, if you overwater you can't just remove it. It's hard to fix especially if your plant is NOT in flower where at least it'll consume a ton of water in 5 days if its actively growing. Overwatered veg plant are just chilling unless you're really pushing the growth in my experience
But yes it's all about the roots/microbes not breathing. In soil it's just hard to fix quickly
@@carrottoponcrak Apologies as I wasn't clear when I mentioned Drainage. I was speaking about good Drainage in your media. Keep growing✌🏿
I love a good pedantic argument.
Did you guys know that ' Sativa ' and ' Indica ' are labeled incorrectly ?
The correct botanical term for ' Sativa ' is 'Cannabis sativa var Indica' and it refers to the tropical/south East Asian variety.
' Indica ' is actually classified as '. . . var Afganica' , and theres a third variant called ' . . . Himalayensis' .
Ruderalis is just a botanical term for a wild type plant.
And another thing , all of those sativa/Indica ratios on the seed packs are completely made up . I've seen no genetic test results. Even if they were using the correct terms , how could they possibly know ?
if anyone can help me get into the cannabis industry let me know! I'm currently in an illegal state, however, have a huge dream for marijuana as well tons and tons of knowledge for it! If I can not find someone to lead me into the legal industry, I will probably begin in the illegal. Just because I absolutely love how marijuana works, grows, affects, and looks!

Can a tall plant be transplanted to a different location, if so how?
A plant dolly a wheel barrel a truck
Can I grow year round in a green house
@@mill8277 yes that's the point of gh in winter they warm up to maintain healthy decent growing during the winter
I’m having rusty looking spots. Is that a calcium thing ???
Hope this helps. I had the same problem. When humidity is too high, the rate at which plants draw water from the soil is reduced because transpiration is slowed by the smaller-than-normal water gradient between the plant and the atmosphere. This can result in diminished nutrient uptake efficiency, which can lead to nutrient deficiencies. I fixed it by getting a dehumidifier and watering once a week instead of 2.
Up your calmag and use some Epsom salts close to flower
To answer your question YES
He mentioned how some growers wanted to put the plant into a Nitrogen deficiency going into flower, what did he mean by this?
Generally he meant that you would like your plant to be running out of N as you get to flush or finish. I begin to reduce when I estimate the plants have 3-4 weeks to finish
I only use nitrogen in small doses if the plant needs it during flower. The first weeks of flower I like to cut back on nitrogen to make room for phosphorus. If you use heavy nitrogen with phosphorus your ppms will be in the danger zone and the plant doesn't need much N anymore in this phase. "The cannabis plant uses 80% nitrogen in veg." According to Harley Smith.

@@koalakyle19 Try FOOP organic fertilizer. Pre mixed liquid all staged for veg bloom and even has sweetner (sugar) additive. A starter pack is $99. Been using it for 2 yrs. The trichomes and yield are worth every penny plus less headaches.....Peace
Just let me in that green house with a pallet of joint paper. When I am done, you will no longer have any plant issues.
How can I get my outdoor plant into early flowering?
If small enough a garbage can over it. Or if big use a tarp.. light deprivation!
Light deprivation (light dep) is a cultivation technique that takes advantage of a plant's photoperiodism capabilities, tricking it into flowering sooner than the natural cycle. This is accomplished by simulating the day and night cycles of late summer months with photoperiods of 12-hour light and 12-hour dark.
Look up... light deprivation

@@davidbabin1287 my plant is covered with greenhouse nylon. can you show me an example? instagram?
One thing I've never read is how much water/nutrient mix should be given. For example I have several plants in containers similar to those in the video. When I mix the 5ml/liter solution as an example, do I mix 12 liters of water for a 40 liter pot or give the plant 1 liter? The concentration is the same but the amount of water is obviously much less. In my opinion the plant also needs water with said nutrients but to what volume? Should we water until it runs out the bottom?
@AL Capone Thanks for the reply. To be honest I haven't heard of Remo specifically but have looked at other two or three part nutrients. I'm currently using Medi one products and recently purchased some Gaia green bloom.
I have an EC meter and often water through and measure the TDS. Even then I feel getting a consistent feed and water schedule is elusive.
