Help Diagnose White Circles
I got a couple beautiful african violets at the nursery two weeks ago. They have been doing very well and have been blooming like crazy, but this week I noticed white circles forming on the leaves. Any ideas what this could be? It doesnt look like powdery mildew to me, but I am new to African Violets. Any help would be great.
Should I spray the leaves down and clean them off? What would be the best solution?
