I had N deficeny in my plant. I have that same shultz stuff which I beleive is to high of N for flower BUT it might be good for your plant right now because it may be lacking N.
I know they have to be kept real humid and I saw on a video where this dude was spraying them with soda water. cus it contains Co2. Hmmm..... I have been misting my plants with that every other day.
I have 6 CFL on 1 plant in flower and I need more it isnt enough.
I think 12 cfl on all your plants in veg is ok but once they get into flower, damn do they grow
