I am growing some ghost peppers and I noticed that there are purple spots on the skin. The soil I am using is Pro-Mix premium vegetable and herb mix which has food for 3 months. I'm 100% sure that its not over-watering or the lack of water because I check them out every single day.Would it be the fact that my plants are exposed to sunlight too much ? They get sunlight in the morning around 6 a.m and to 8:30 p.m. I'm sorry about the poor image I will take some more today but the picture you see here does have a little purple and its my pepper plant that the peppers are less exposed to sunlight while the other plants do have some peppers with a lot of purple on them which are highly exposed to sunlight.
