There are a lot of things to consider. The type of AG, type of pepper. For that size AG, I'd only keep one pepper in there, especially for a chinense, which that looks like. I'd try to keep as much canopy under light as possible. You can make clones from the cuttings if you want. The roots might benefit from a little pruning too. I would completely change the nutes at least every week. For a chinense plant, it'd do better in something like a Bounty (An Ultra/Extra at the minimum) that has more vertical space to work with, bigger light and bigger res. Even with the Bounty, I've had one that totally outgrew the basket, main stem got so wide it started blocking water flow. It did produce some pods though. The pics look very cool, just have to manage it the best you can. It's probably at the point, if not will be soon, where it's too late to pull it out of there. Good luck, and please keep us posted how it does!
