I used Miracle Gro for Flowers and Vegetables, which has nitrogen, phosphate, and K2O for all the peppers I planted. I gave two other pepper plants (same size containers and same type of soil) to my boyfriend, who has them on his third floor balcony where they get more sunlight and seem a bit drier than on my patio, and his have some nice peppers coming. Still if anyone thinks they can identify the moisture-related affliction on my peppers and tell me what to do about it, I would really appreciate it!

Mexibelle(?) perhaps? A hybrid that looks like a common red bell pepper but develops ''hot'' when left on the bush.

First thing I'd do is look for pests - especially spider mites. You will have to look closely as they are quite difficult to see and what you usually notice first is the fine webs on the underside of the leaves. Is this growing indoors or out?

poster, your location IS displayed! I think you got enough tips from everyone else. I guess a watering issue is the consensus. I am good ol' hot Los Angeles, and I water mine daily. My peppers are doing well, except I have a resident gopher or vole, who has stolen two of my coolest, nicest hot pepper plants, poof gone~. In my case, no wilted leaves except on the ones that the dog plowed up trying to get to the gopher! I hospitalized them and they are slowly recovering. Like someone else said, perhaps remove the messy leaves, and hope for improved growth. I have been on youtube and found videos on baking soda treatments, neem oil treatments, and aspirin treatments for garden plants. I have used all of them, each for a different purpose. Check youtube out as well.
