My pH seemed to creep up to about 6.5, and the leaves started to curl a little, and there were spots of brown on the edge of one leaf. Not sure if this is a nutrient or pH issue? The PPM hasn't really gone down much (about 5ppm), but pH seemed to rise. Sorry for the bad camera work, my girlfriend has the good one because shes on a trip. pH: Was 6.5 now 5.9 PPM: ~200 MaxiBloom, 50 Silicablast, ~5 B'Cuzz Growth in 6 gal. water.
