So I have a big cayenne plant in a pot, with about 20-25 dark green fruits. Note: none of them are red yet.

Anyway, I've noticed its stopped flowering. In fact, three baby pepppers have turned yellow and dropped. Note that I don't consider this a dropped blossom - it seems like the 3 peppers fertilized, grew a little bit, and then died off.

Do you think the plant is all done? I still have two months left before frost and hope its not done producing. Should I fertilize with tomato miracle-gro or epsom salts?
