What is this and how do I get rid of it?
I have this powdery growth building up on my pepper plants and now my mint. It's mostly white, but sometimes black, and leaves little webs and sappy stuff all over the leaves. Occasionally it builds up into little balls that hang from the leaves. Is it a bug? Or is it some sort of mold? My flowers all seem to be ok but the rest of the plants are losing leaves like crazy.
