I have several hot and super hot varieties growing in 5 gal planters. They were all doing well until my reapers started getting yellow leaves. Some leaves are dropping aswell. It has been much cooler lately now that it is late September but the others at still doing well. They have been growing in identical conditions. Why would my reapers be affected more so? There are several green pods left on them and want to see them mature. Any assistance would be great. Thanks!
