This has been driving me crazy. One of my peppers is not doing well, but from the research I've done, I can't narrow down whether or not the issue is too much light, or too little water. Neither problem makes sense, as the pepper next to it is a good 8" taller and can't get close enough to the light, but at the same time, the troubled plant *isn't* drinking water. I've included a picture, you can see the leaves are curled. Additionally, inspite of putting a fan in the area for the last month, it's still got what might be Edema on the underside of the leaves. It's not bugs, and the other plants don't have it. (for reference, the plant in the foreground is a Golden Cayenne, and the tall one in the back is a Red Cayenne.) If anyone has any knowledge they'd like to share, I'd love to hear it, otherwise I worry I may have to put this one in the compost.

Don't give up too soon. I ve seen them rise from the grave or close anyway

Too much nitrogen and/or potassium can also do this, as well as too much light on young leaves in aprticular or aphids can all do this.

Not enough root massaging! Couldn't resist! My wife works at a greenhouse...and not that she knows everything...but she said her guess was overwatering or aphids. I told her you said there were no bugs, and she said "Okay...but it still looks like aphids!" - She said you can check for root rot also. She said if you expose the roots and they look brown, then maybe it's root rot. (I didn't say this to her...but I'm thinking the roots are going to be brown from the dirt! LOL)

I don’t know, but I think I see aphids on the underside of many leaves.

I know they may look like aphids, but they aren't. It's isolated to this one plant, and whatever is on the bottom of the leaves is difficult to scrape off As for getting too much light, that's something I don't really understand. Both plants are Cayenne peppers, just different color peppers, and the taller one doesn't have any of the leaf curling etc. It's odd. The whole thing is hydroponic (roots are bedded in vermiculite and clay pebbles). I might see about transferring it to a nutrient-water-only bucket and then move it, but on the other hand the red Cayenne is going to have about 80 peppers pretty soon and I've got more than I need, plus I am needing space for another 8 plants I have growing.

The excess light is more of an issue for young plants. Maybe since they are two different peppers the one having problems is a younger plant.
And peppers do best is real soil with low nitrogen. Nitrogen will stimulate a lot of foliage growth but at the expense of fruits, and if the roots are not healthy or developed enough they will not be able to handle a lot of upper growth. The hydroponics solution may be too nitrogen rich.
I would move the plant to actual soil, or dilute the hydroponics solution and add some super phosphate for root development.

The problem with the nitrogen issue is that I have sprouts, and another larger pepper all using the exact same solution. This is the only plant among about 8 that is having this specific issue. Same regarding the excess light. I have a number of plants that I'm having to take special care off because they started to get leggy (due to wanting more light than they were getting). Moving the plant to soil will likely kill it, unfortunately. The two Cayenne peppers I have are around 8 or 9 months old each, and at this point, being that I have about a thousand cayenne seeds, if this one gets moved to soil it would likely be better to just compost it and start over.

Flash assisted closeup of the leaves: The plant is still growing, and has between 50 and 80 flowers on it, but it's also not looking very good compared to the day I took the first image at the top of the thread. I've moved it so that it is around a foot further away from the light than it was. this stuff is almost like it's sugar coated, but it doesn't scrape off very easily. This plant is pretty much a complete loss, but I am hoping to figure out what is wrong with it so I can avoid it in the future. It may be that there's something going on in the roots that I don't see. Just really annoying when you use the same materials, the same setup, the same nutrients, the same same same, and one plant that was historically doing well (this one got peppers 3 months before the red one did) suddenly has weird issues.
