Both of my mint plants have mold and as Iooked closer you see thin larvae type beasties. On one plant it was all through the plant, the second one I’m trying to salvage. I have noticed small black bugs around my plants and my arugula was brown a d dying. I did not get a photo of that. But I have attached photos from my mint plant. Should I be rotating the covers to prevent mold because my tomato plant has mold too but no beasties. I’d love it if someone has some thoughts because I am concerned I’m going to lose more plants. Thank you
