I have begun to notice pinprick black spots on the underside of some of the leaves on my jade plant. I recently began treating it with 70% rubbing alcohol daily and neem oil weekly for spider mites. I increased the watering, and with rainy and humid days, I may have caused a fungal infection of the plant. These spots do not seem to be spider mites but something different. As I have continued to treat the plant, the spider mites are almost completely gone -- and the spots are part of the leaves, not crawling like the mites I did see. I can't identify if it is a fungal infection or something else.
