Ready to be flipped. Dropped the light down to 36 inches and have it dimmed down to 60%.
Gave them another haircut and took some cuts in case any of these phenos turn out to be a keeper.
Also gave them a foliar application of Chitosal.
Everything cruising along and all the plants look happy and healthy with vigorous growth.
I'm not sure if this is nutrient burn or a cal/mag issue (deficiency or lockout), or something else. Anybody know what is likely to be causing this, and how to treat it?
I don't think it's a cal mag problem. It could be due to using up the potassium. I would be tempted to leave your nutes as is but increase the bloom slightly and see how that goes.
