Hey guys running a 600w hps light with green house seed co Big Bang auto flower. Gave it veg nutrients (i know i should change to flower nutrients) i will next feeding. I water 2x a week about 1.5l to the big one, (small which are clones of the big get 350ml) ligts are 18/6. This over water or just a nutrient screw up? Should i just do a flush and feed with flowering nuts? Sorry for the pic hps lights make it hard, ill pull it out to take more
