Whatever nutes you decide on, my advice is to not make the solution too strong. My total nutes run 700-800 ppm. If you run full strength nutes according to the labels, you are up in the 1500ppm range which is too high for hot peppers.
My personal concoction that I am using right now with good results is equal parts of GH flora duo A, and B and Cal-mag+ for a total concentration of 7-800ppm. That is probably heavy on the calcium, but the plants really suffer if they get calcium deficient, so I am erring on the safe side.
