I have a tiny bumps appearing on leaves of my After Dark and a Donna Wise x Susan Fucks. There are also a couple of very small spots. The After Dark is starting to droop. I moved it to higher light and put it closer to a fan. So far my treatment has been a spray of Bayer 3 in 1. I know mites are usually the culprit, but I don't see progress. Any ideas? this is only my 2nd season growing these.
