A new wrinkle...
Last night as I was picking a small batch of peppers I found a small hornworm working its way around one plant. It would have been invisible except it had wasp larvae on it. Hopefully this will help some because I have been tossing too many peppers this year.
I may have a combination of things happening, the sunburn and this sneaky little bugger. This weekend the plants are getting a real close examination to see if there are any more hornworms on them.
