A picture would be of great help in trying to access the issues with your plant. There are several possibilities of what is causing it. They range from stress to spray drifts. 2-4-D damage can be similar to what you are describing but again without seeing a picture I can't really give a good opinion. If you have them at an online hosting site you can copy and paste the link in the optional link url box. As for adding a picture to your post I will let one of the more computer knowledgeable posters tell you how. Jay

Hopefully you can see my picture from here...

Here is a link that might be useful: Pepper plant

I'm going to guess that the soil is too wet.

I'll jump in and third that! That was my first guess even before the pic, but since I hardly ever grow peppers I was waiting for some to the Pepper Experts to weigh in!

After seeing the pic I would say environmental/climate stress. Really nothing wrong with that plant. Moisture can have an effect but peppers don't like cool nights especially the chile types. Some warm weather/bright sun and this plant will be fine.

Help! What is causing my leaves to curl?
Thanks much

Aphid damage?

This may be a little late, but did you check calcium? Your plant looked large enough to be deficient in things, and this looks like calcium maybe.

Mites? Check both sides of the leaf.

If it is mites, try Azamax or an organic pesticide.

What happen with My Capsicum plant.. anyone help me ??

I don't know about the shredding but the leaf down near the soil surface really looks like a leafminer has set up camp. They have to come out of the leaf sometime, maybe shredding then results. Don't know.

My experience with leafminers hasn't been on peppers. Spinach, beets and chard are sometimes plagued ... I just take the leaves off and grind them underfoot.

Here's something from from the U of Minnesota on this idea. LINK They list peppers.
