Not sure if it was the crop rotation for you but I feel like that shouldn't have effected anything as long as you put nutrients back into the soil...I planted banana peppers and bell peppers this year and the bell peppers were amazing producers while the banana peppers were an utter failure....same thing for me---leaves were yellow and fell off, barely flowered, didn't set fruit...I think i got two banana peppers total...it was pitiful...while right next to those plants, the bell peppers took off, easily growing 4 to 5 on each plant at a time....who knows. I personally think they are just difficult to grow or maybe it was an issue with the starts I used.
