I had the same spots on my plants but worse. I blamed it on the soil being too dense. When I encountered this problem I went back to the store and purchased more pepper plants and stuck them in miracle gro potting mix and they have thrived without any issues. With that said, all of my pepper plants that were in the "topsoil mix" that I bought from my local mom and pop store, have turned around for the most part and thrived. I believe this happened because our weather got dryer. Only two superhots are still kinda struggling but doing much better and flowering. This is my first year gardening so I'm learning step by step. But like I said, too dense of a soil mix I believe caused fungal problems for some of my plants.
