I would spray the plants with a copper fungicide just in case. There are so many weird pepper ailments that I can't keep up with them. Almost every year I see one I haven't seen before. I have never seen that in all my years growing Jalapenos so I don't have a clue what it is. I have however seen similar things on bell peppers caused by stings from leaf footed bugs. I have seen BER on bells before but that didn't look quite like what you are showing but maybe it manifests itself differently on Jalapenos. On my bells when they have shown BER they looked very similar to what happens on tomatoes with the blackened blossom end and stunted growth.
