First post for me. My wife and I decided to try our hand at peppers in containers for the first time this year. Got started a bit late in the season, and we had a brutal summer of heat here in Phoenix. So, it's been a bit rough on the plants. Out of 10 serrano and 10 jalapeno seedlings we had going, we're down to 2 jalapenos, and 4 serranos. Have 1 strong jalapeno and 1 strong serrano. Both have finally started to grow flowers, and our jalapeno has 2 little peppers coming in.
I just went out to check on them, and I noticed some odd discoloration on a few of the leaves of our strong jalapeno. Currently seems to be local to just that one, but I haven't seen anything like it before, so I'm a bit concerned. We fertilize every 2 weeks with fish/seaweed emulsion. The only other thing that's different recently, is I did spray them the other day with an epsom salt mixture now that they're starting to flower. I'm wondering if the leaf issue is do to the epsom salt mix? Maybe it was too concentrated or I applied too much, not sure. If not epsom salt issues, then I'm back to tracking down the culprit. Done a lot of research about varying disease and pests with peppers, but I haven't seen any pictures that look quite likes this. Any help would be much appreciated. Thanks in advance!
