And to be clear, the stuff on mine didn't start out fuzzy at all. The picture is of a prolonged case, after the plant had been chopped for over a week. I have other pots that I haven't disposed of yet. It looks exactly like Myke's. He's growing in organic soil and I'm growing in coco. He's using a sips setup, I was using Blumats. His is bottom fed, mine is top. The only shared factor is a constant water source.
