now I could be wrong but to me this looks like it's started to flower already? it's day 14 today and they've just started getting actual nutrients
day 18 and had to pull one as it was looking very strange and the buds started to turn really black but in a strange way
do you suggest keeping it as 24hr under LED? I normally keep fems in there for 24Hrs then move to main tent that's 18/6 or 12/12 depending which stage of the plant? I use the smaller tent for 24hr LED while I clean the other tent out as normally I've got them drying
