Transplanted into the 3 gallon medical buckets from thebucketcompany. Everything still going smoothly. Plants are happy under the gavita at 40% power and 50 inches above the top of the plants.
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.
