GMSgrowsanswered grow question 4 years ago If all your hairs turn red, orange to early it's usually a sign of to much nutrients in early flowering. I dont like to see pistols changing colour until the 5th 6th week into flower. So remember for your next grow, to start your flower nutes a little on the lighter side for early flower, ramp them up a little for mid flower, and back down for late flower. Underfed you still get nice big fat nugs. Over fed and the yield suffers. Cheers
