Thanks for the reply...I just checked and Tiger Bloom has 0.5% Magnesium...I switch nutes cause peters is too strong (I thought) especially for flower, and it has too much N. Also, I start out with dilute nutes (I was under the impression that good soil should have at least 3-4wks of nutes for the plant.) and move up as flower continues. Its just that this is already starting again, with dilute nutes in good organic soil. So no nut burn, no excess, and should be no deficiency. ??? Its a mystery. I'll just keep trying different things, I guess

Thanks for the suggestions...I will add some epsom salts to a plant or two and see what happens...
dlg256 Reviewed by dlg256 on . Yellowing leaves. This starts to happen after about two weeks in flowering, see pic. I started using only RO water (thinking nutrient lockout) and minimum dosage of Tiger Bloom (2tsp/gal). The leave on the left is from 2 wk flowering and the other is from an older almost done plant. I still get decent buds, but something isn't right. Can anybody identify problem by looking at leaves. The room is not hot 75-85, and i only use dilute nutrients. Peters 20-20-20 during veg (about 1/4tsp/gal). Thanks Rating: 5
