From my experience, pepper plants love a more sandy soil, or as close to loam as you can get, great drainage, moist root balls, and foliar sprays with Calcium, Magnesium, and Sulfur. There are recipes online on how to make these kinds of things with Magnesium and Sulfur being the easiest ( Epsom Salt).
They love consistency, but also love spontaneous changes in something they get regularly. As in, I keep a written garden journal, and every so ofter I put a day in there of less water than usual, or a bit more fertilizer with more water, etc. They seem to really thrive the days or weeks after that putting out pods quicker and ripening them faster.
As for fertilizers, I like organic. Fish Emulsion for one is a good start but supplement with other ferts doesn't hurt, just watch the ratios. I use a fertilizer in the sol made from organic products, fish emulsion every 1-2 weeks depending on how they're looking, kelp emulsion, and other things from kelp4less.com because they are just awesome!

Now when the plants are all grown and are just flowering I use one fertilizer I tried last year that was great!

These are just some ideas of how it can be done, and all plants are different, even in the same garden, some love the Fish emulsion, others the Kelp, and others just the extreme blend mixed with something for Phosphorous, which is why I listed so many! You have to give your plants options to know what makes them thrive.
