Q.Bell Pepper Fungus?
My bell peppers start to brown with crisp edges between the brown and green areas. In the center of the brown areas, there is a dark spot. It doesn’t look like blossom end rot, but then I haven’t ever seen blossom end rot in peppers before. What do you think this could be?

It could be blossom end rot. It may also be sunscald. If you have had rather intense heat lately, you may want to set up a sun shade over the pepper plants to help prevent sunscald. Increase water to the plants as well to help combat possible blossom end rot.
