I think you may have 2 separate problems, judging by the photos. The white spots are probably powdery mildew, which is a type of fungus. If you're not growing organically, you may wish to treat with daconil; there is one specifically for fruits and vegetables, so use that. It's very effective. If you are growing organically you may, as suggested, try neem oil. However, don't apply it in sunlight and don't apply it if you expect temps over 90 degrees Fahrenheit, or it will burn the leaves. You may want to try a sulphur-based insecticide. "Safer" puts out one of those, but read and follow the directions, and make sure it's safe for vegetables. It is treatable if you start working on it before it invades lots of leaves and weakens the plant. =================================================== Now, about that pepper plant. It could also be powdery mildew or it could be another, more serious disease. If you're not seeing white and/or diffuse yellow on the leaves, then it may not be powdery mildew. You folks in the south get some plant diseases that those of us in the cold zones rarely or never experience. I'd feel a lot better if someone who is familiar with your part of the country would chime in. I hate to speculate, but... First, if the pepper is planted in soggy ground that does not drain well, that could be your problem. If the other plants around it are not having problems, I'd suspect a virus, root nematodes (we don't get those up here), or soil-borne bacteria (we rarely have to deal with that either). I don't like the way it is wilting. If sitting in water is not the problem, I'd suspect a systemic plant disease. I'm sorry to say that you may have to destroy the plant if it doesn't improve in a few days (and I doubt it will). By "destroy" I mean you must dig it out, root and all, and put it in the trash. Don't compost it and don't leave it around; if it's diseased you don't want to contaminate other plants. Since peppers are related to tomatoes, eggplant, and potatoes, it may infect those plants if you have them. Try googling "peppers wilting" and see if can diagnose the problem. Again, I don't have any experience with some of the diseases that are common in your part of the world. Link below to University of Florida info on diseases of peppers in FL. Best of luck.

Thanks everyone for the comments! The pot is a 15" diameter, what should it be? And I have been hand pollenating my zucchinis since the beginning as I am not sure if the bees are doing it. The one in the picture never had a flower that opened, it just turned brown and fell off.

I have same problem on one of my okra plants (Fife Creek Cowhorn). On mine it was 2 different types of aphids. The ants were so bad I had to use tanglefoot on the container so the ants would get stuck before they could get to the okra plants. I think you acted too soon. Okra can take a licking and keep on ticking. I grow 5 different type and only one plant of each so I can not rip any of them out. I wish you much better luck next season. DL

chinacat, rubbing alcohol costs about 75 cents. it's worth it to have around for first aid purposes anyway, and a bottle will last you about a decade. bottom leaves die on AVs. It just happens. I think I read somewhere that AV leaves have a life span of about a year until they shrivel up and die like yours have. Generally one should repot their AVs every 6 months or so to bury the exposed trunk. If you scrape the trunk lightly with a knife it will grow new roots much more easily.
