Hello. I have this new Echeveria Pink Donna and I don't know what these black spots are. Initially I thought they were some kind of pests and I sprayed the plant with insecticide but I think the spots multiplied. Do you know what they are and what to do about them?
My plant sits on a S-E windowsill under led grow lights. I haven't changed the pot since I got it, 2 weeks ago. I think it came with the spots but there were fewer than now.
