Hello, All plants need calcium and magnesium in order to grow normally. Some water source provide sufficient levels of these elements, therefore they do not need to be added through fertilizer. If your water source is deficient in one or both of these elements, then you will need to use a fertilizer that provides them. First I would have a lab test your water to see how much calcium and magnesium it has. If they are low, then you may need to use a calcium-magnesium fertilizer. The only way to know for sure is to have your plant tissue and growing media tested by a lab to determine if there are any deficiencies that need to be addressed. Thanks :)
Hello, To get the best fertilizer recommendation for your crop, it is best to have the water tested. Some water sources provide plenty of calcium or magnesium and some do not. In Addition, the water alkalinity (measure of the bicarbonates and carbonates in the water - which is also a measure of the dissolved limestone in the water) strongly influences the growing medium pH. Fertilizer is used to prevent the water alkalinity from causing the pH of the growing medium to climb (see our other videos which explain this). Bottom line, we do not recommend fertilizer unless we know what is in the water. Without this information the water can cause nutritional problems along with a fertilizer. Thanks
@@anupamdas3222 The rate of fertilizer application will vary depending on the crop and the analysis of the fertilizer. When using a complete fertilizer (which includes N-P-K and micronutrients) we often refer to fertilizer rate based on the parts per million of nitrogen. The rates below are based on applying a fertilizer solution to the growing medium until the growing medium is uniformly moistened. For crops that like higher fertilizer rates, such as vegetative petunias, you can apply a nitrogen rate of 150-250 ppm. Assuming the fertilizer is balanced for the needs of the plant, this will provide all the other needed nutrients at the correct amounts. For marigolds and dianthus that prefer lower fertilizer rates since they are started from seed, the proper rate is 100-150 ppm nitrogen. These rates are meant to be applied to the growing medium at every watering. Thanks
Hello Appu, We are not sure if the calcium nitrate application will have a negative impact on the flowering of your grapes. We suggest to consult with your State extension service as they may have people who have experience with grape production. Thank you

Hi Britney! Potash contains potassium and has a role in plant hardening, flower and fruit development and for robust stems. The term potash comes from an old process in which wood ash was soaked in water and then the water was evaporated in an iron pot (“pot-ash”). The residues left over had a high concentration of potassium that was used as a fertilizer. This process is no longer used, but the name is still used. Potash is simply a potassium fertilizer, which is one of the three major elements (macronutrients) that plants need in order to grow normally.

Hello! You can supplement with Gypsum, but it will not last more than 2 months. The best way to make sure there is sufficient calcium is to use a water soluble fertilizer or water applied organic fertilizer that provides calcium.
Do you have any recommendations for a water soluble calcium fertilizer I can use in conjunction with the CRF Osmocote Plus? It has a high nitrogen content so I worry about using calcium nitrate.
calcium is very heavy so it need a lot less to make up lets say a hydrogen. Also that plant needed a bigger container not calcium. Bonsai get around this by cutting and raking the roots
Excellent video as usual ! I am amazed that you take this complex science and brake it down in a 2-4 min video. Thank you Thank you Thank you
Thanks for your feeback :)
You're the best!
Excellent explanation
increddible very helpful and no bull shitting with pointless jokes
thank you for sharing valuable information
He's wrong about the pH. Calcium Carbonate drastically raises pH, as well as Limestone.
Can I use my calcium supplement and magnesium supplement on my plants?

It depends on the EC of your mix.
Hello sir can you suggest me fertilizing schedule for flower plant seedlings.. Like marigold, petunia, dianthus etc

@@PROMIXGreenhouseGrowing the basic means how often should we spray like npk 12:61:00, or 19:19:19, humic acid etc

How often should we use PGR after plantation of flower seedlings..
I hv sprayed calcium nitrate to my grape plant... Bit top get color changed... Does it effect to the flowering

Happened with my container watermelon.
Really disappointing to grow so many months only to have the fruit rot.

Hello. If using water with less than 40 ppm of calcium and/or reverse osmosis water would you recommend supplementing Pro Mix BX with gypsum?
