I've got ghost, Trinidad scorpion and carolina reaper plants that all seem to be suffering the same problems. The ghosts are dropping yellow leaves, but the new growth is fairly dark green. The Trinidad scorpions leaves are turning brown and drying out starting at the tips. And my carolina reapers are doing the same thing as my scorpions.
I'm container gardening all of these plants, and they are individually planted in 5 gallon buckets. My soil is a mixture of potting soil, cow manure and sand all mixed together in fairly equal amounts. The manure is store bought so it was 100% ready to be used. I did spray the ghosts with 1:1 water and rubbing alcohol because I think they have spider mites.
I will update posts with photos in a day or so, but it's wet, cold and miserable here in Ohio today. Any help would be appreciated
