I always start much weaker with the nutes and build up to full strength over a few week period. You can always tweak up your nutes but you cannot take it down real easy if overdone.
So are you saying that I should start weaker than 1.5ml per gallon. Thats what the General Hydroponics feed chart suggests for seedlings. If so, how much would you suggest?
