I tried a search, but leaf yellowing has been blamed on everything under the sun, so thought I'd ask more directly. A few of my plants are having their leaves start to yellow, most obviously along the center vein of the larger leaves.
My plants are coming due for another round of ferts, and I gave them half-strength last time. Over-fertilizing is not a likely cause of their problem. Could under-fertilizing cause yellowing? It'd be great if that solved itself with something I was going to do anyway.
There was also a minor resurgence of aphids that resolved itself with natural ladybug intervention. The yellowing on the leaves is on the larger, older ones, and any aphid damage would likely start to show on the new leaves, correct?
I water a small amount often instead of a large amount rarely. 2L (half gallon) of water every day or two, split between 14 plants. Overwatering could be a theoretical cause, but the yellowing isn't on the plants that have stayed wet. A few of my plants just never seem to dry out due to positioning, minor shade, etc, and they appear fine. (I skip watering them if they're already wet, but there's no doubt they've been moist longer than the ones with yellowing)
A couple weeks ago we had a cold spell, and it got down to mid 40s F outside. No frost, but I'm not sure if pepper plants turn yellow in the fall naturally, or if that's just a native plant reaction. None of the native trees around here are noticeably yellowing
Any advice is appreciated.
