Hi, I have one ghost pepper plant (labeled Red Bhut Jolokia when I bought it as a tiny plant). It currently has 3 good sized peppers on it, about 2 inches long each. After the peppers reached this size, they went from all green to having purplish streaks on them. The purple is becoming more prominent. I searched and it doesn't really look like rot to me and I can't find anyone with the same issue. I saw that there are purple varieties but this was sold as red. Could they be turning this color before they go orange/red? Are they getting too much sun, too much/little water etc? I'm really new to growing hot peppers and have only grown habaneros before. Thanks!
