GG4

Getting some frost. Stacking and bulking. Fans are turning yellow. pH has been good. Water and EC dropping simultaneously with a slight pH climb. Started giving her cal mag, upped her bloom and decreased her micro, which hasn't helped. Looks like a magnesium deficiency and possibly phosphorus, hence the dietary changes. pH has been normal, she's been flowering for 5 weeks, possibly normal redirection of resources. I'm concerned about purple leaf veins, petioles and pistils have a pink tint, which didn't occur the last time I ran this cultivar (same batch of seeds).
