Hey Deja....
watch your ppms.....are they dropping daily? If so up your nutes. I had that happen in my grows with the CalMag/ProBloom....turned out I was too LOW in nutes and the plants got what i THINK is a copper def....the newer growth wilted. Is it like that? I bet its same damn thing.

I found I got the problem in later flowering if I let my nutes go UNDER 1000. See the buggers were EATING the nutes down and when the number got to low they''d look wilted. (they were eating a couple hundred a day down.
