What's wrong with my echeveria?
I can't figure out what's wrong with this plant. I got out my magnifying glass. I thought it was mealy bug, but no legs and doesn't crawl. I thought it was white fly, but no wings and doesn't fly. I can't see an insect at all. The black stuff seems to be soot or mold of some sort. I poured soapy water on it today, but I'd sure like to know what I'm dealing with!
