Just noticed today that there was a white powder substance on top of my soil. It's not fuzzy or mold I don't believe. I hae been using RO water and no nuets at all anyone have an idea of what this might be good/bad? Hope it's nothing major from what I read it's just salt build up possibly but I have been using RO water will this still happen?
