It looks k like a fungus to me. Can you put your peppers in the sun? Al

My neighbors house blocks all sun to my house. Albany is a poorly designed city. I have a cold frame, but I just checked the temperature and its only 54 degrees, which is way too cold for the peppers.

If it is fungus can spray fungicide. I know Copper is effective against fungus. We had lots of rain in our area and My fruit tree flowers are completely wet. I am worried from Fungus and Brown Rot. Although I don't use toxic spray normally I was and hopefully will be successful with Surround spray. But I think in this case I have no choice.

Well it ended up being sunny these past two days so I did get them out in the cold frame, and I sprayed with fungicide. The brown spots are causing the leaves to curl. I think I'm going to pinch off the bad leaves.

I would tend to agree with you about the 54 degrees thing. Anything below 70 will cause pepper seedlings to have stunted growth & they will never be the same again. I tried putting mine out in a cold frame when temps were getting high enough last year. A little bit of cold destroyed every single one of them. Could also be a fungus though. Pinch off the bad leaves, get them warmer & give them a few days to see what happens.
