C major Lydian 4th scale degree with fret numbers

in the key of G major/ e minor I just gave examples of how to play
in the mode of C Major Lydian. explaining how the notes should be correct
if you end up landing on the 12th fret. Explained how its a major chord not a minor chord.
I even made a mistake when the e minor chord was playing I didn't play in a minor mode and you could hear that I played a few bad notes
