Hi, I have several small Cacti and they are not doing well. First, they started with brown spots that looked like Mite damage but even with a high power magnifying glass, I never saw one Mite. I sprayed several of them with Alcohol a few times and I'm not quite sure if it helped or not. I put several of the problem plants outside for the Summer and they are doing better but now I have one with new growth but it has developed red spots on the older clades. Previously, the plant was exposed to too much sun indoors and turned red. They are now outside with minimum sunlight on a covered porch. I'm thinking they could have a virus? Also, I had what I think was a Fungal issue. See pictures attached to see the Fungal, Mite damage and the red spots. Thanks, Cathy
