My jumbo jalapenos are rotting on the tips before they get mature. I googled it and found out this could be to a variety of problems including soil deficiency. So I put a fertilizer in my soil that had nitrogen and other stuff in it. They are still having this problem. I am not over watering my peppers either. I have some habaneros and a couple other varieties in the planter Box and they occasionly have the same problem but the jalapenos are by far the worst. I can't even get enough of a crop to do anything with. Any suggestions?
