You’re a brave man, LOL!
What do you use for fertilizing your peppers? I usually grow only sweet peppers with a few Jalapenos and maybe an Ancho/Poblano on random years.
Mine respond well to a handful of crushed eggshells in the planting hole (mine are in raised beds) and then a top dressing of Bone Meal twice during the growing months.
I do the same for my tomatoes. No blossom end rot and they all seem to produce just fine without any additional fertilizers. I do add compost to the beds every other season, though.
I treat my peppers as if they were tomatoes. Same nutrients same soil, etc. Since I grow everything in pots I just root prune and change the soil out every couple of years.
Have you seen the colored Jalapenos developed by the botanists at New Mexico State University? I grow them to put a bit of color onto the terrace. You can buy seeds from New Mexico State University's Chile Pepper Institute or I can send you some if you're interested. Here is an article describing how and why they developed the 3 varieties: Chile Pepper Institute
