i usually post in the bonsai section, but i grow vegetables every year as well, and this year i decided to grow banana peppers along with my heirloom tomatoes. The pepper had some bug problems early in the season which i took care of, but now it seems something different is going on, particularly in one plant (it's actually the biggest one also). The leaves seem to be getting brown spots in the middle and at the edges...almost like a burn, but the problem is it spreads. Here are some pictures:
(sorry the last one is a little blurry)
What do you guys think the problem could be?
