I have been having this issue only with habaneros, all my other plants are doing great. The issue is that I grow beautiful plants, healthy fruit set and production. When I cut open my habaneros (brown ones in particular), all i find are brown small deformed seeds or none at all. Sometimes they are small tiny white seeds that are almost mushy. The plants are getting the same nutrients as all my other peppers and healthy in all other respects. I suspect high temps may be an issue but I cannot find anything on this subject. Most of my peppers are netted to prevent crossing. This brown one was actually left unetted and isolated by distance. Do extremely high temps of 99-102 cause this?
