Looks like calcium deficiency to me. Treat your plants with calcium chloride, sold as Blossom End Rot solution.

I was hoping that was the answer bc I had the same problem last year with some peppers and thought maybe thats it so I put a little land plaster in each hole this year and a little bone meal when first blooms appeared so I'm glad to hear I'm on the right track

can that blossom end be added to a watering can?...or does it only have to sprayed on?

Thanks for the replys. I know it's difficult making a call w/ just a photo...Anyway, after more research I to believe it's a calcium shortage. Being strickly organic, and not wanting to spend money on a calcium suppliment that I've never needed before and may never need again, I'm going homemade...I'll Powder my used egg shells, 4-5 per plant, and sprinkle around the base of each plant...This will keep it organic and should supply the needed calcium for the pepper's. I'll keep ya posted.

Thanks and HAPPY 4th!!! We live in the best country on earth...

Egg shells take a very long time to break down to a usable state.

Gypsum is an organic product that can be bought at most hardware/nurseries and breaks down somewhat quicker. You can also recycle sheetrock interior wall panels for their gypsum. Anybody that remodels interiors will gladly give you all you want.

Sterilized Bone Meal is also organic and reasonably fast acting, though not free.

The liquid products will work quicker, and yes sandpebbles, a watering can can be used.

jwmeyer: I use bonemeal in potted peppers. It also looks like your pepper may have sun-scald.

I warn against using building materials to derive your gypsum from bc the paper is put on with glues and there are all kinds of nasty additives in it to hold it together and make it tougher. my brother is in the sheet rock biz and I don't think he would dare put it on his garden and he could care less if it's organic or not as long as it grows

In my original response I considered the possibility it could be sun-scald, but I don't think it is. The sun-scald that I've experienced was a slightly sunken, flat tan colored, dry area. His is still shiny and just looks like the problem stems from within, rather than from outside.
