Edema! Someone on another forum solved it. caused from excess water. Close enough madplanter. This is strange because most peppers will die in these conditions. Stranger still, I have cut back on watering them to the point they wilt and one nearly died. It's bouncing back now after losing most of its leaves. As it grows I'll monitor to see if new growth exhibits these symptoms. Might be time to pot up and increase drainage in the new soil. Which is odd because its the same soil mix as the other 147 peppers.
