Somewhat against my better judgement, I've continued to keep the Bell Pepper plant going. It's sitting in an opposite corner of the kitchen from the other plants. I keep thinking about what could be causing it to look so poorly. Something about the symptoms- slightly curled, spotty leaves- made me think it was a nutrient deficiency, I read somewhere made it sound like potassium so I actually chopped up some banana skin, soaked it in water, and gave the plant that. Then I noticed a few perfectly round holes in the center of leaves, which made me suspect a caterpillar but I never found it, or the frass. Next I suspected that whatever is apparently feeding on my plant and taking nutrients might be hiding in the convenient hollow of the bamboo pole staking up the plant!
