HB. what do you think about the sulfur content in dynagro? none is shown on the label, % wise. But I do see that sum of the salts in grow and bloom are sulfates of some sort. I might try to do a round with some well water added to RO, and skip the mag pro. It looks like it might be my only source of sulfur, but I bet my 250ppm well water has some sulfur in it.
