I have 2 Jalapeno plants with an abundance of peppers; however, in the last week black discoloration has started to appear at the joints of stems and on some of the peppers. What is this and is there anything that I can do about it?

One thing that I can think of that could be causing the issue is a condition called stem scald, which normally happens on the main stem. What happens is a heat source can focus heat on a part of the stem and it wilts. It is known to happen when plastic is used and it focuses the heat onto a part of the stem.
