No matter what I do, I can't get my pepper plants to produce peppers after flowering...?

This is a tough question for me, as I've tried so much.
For experts out there who grow chillies or peppers, or have good success and know-how, let me break down my conditions.

First, I'm using Hydroponics in a Flood and Drain system, the system is built from scratch and is flawless in design, so that's not the problem.

Water -> Stable pH of 5.7 (of course it's lower than soil remember this is hydroponics). Seems that should be Okay.

Vegetation Growth -> Fine, vegs good, no problems leaves are green and always in good quality.

NPK -> I've gone and tested this in many formulas, it does not matter, I've used the exact same formula as someone else using the same stuff and his fruits, mine doesn't. So this isn't an issue I am certain.

Lighting -> This may be the issue, in fact maybe it's a bad habit, but I have 24/7 lighting. It never stops, I have mega success with other stuff, but are chillies and peppers very picky about having no light to be able to have the peppers grow from the bud, or starting off that way through pollination or whatever?

Temperature -> I understand that Chillies and peppers love heat, correct? My temps don't drop much though, which could be a problem as well? Day 31c - Night - 29c

They are being fed every 4 hours, for 10 minutes each time, it's automated and just repeates every 4 hours.

Symptoms -> Well after it flowers, the flower obviously dies, but then the bud and stalk falls off with it. I thought it was pollination, but read they are self pollinating anyway, but I tried to manually do it which worked on many things before, but on these it made NO difference, same symptoms. The Cycle is ---- Flowers > Flower Dies -> Bud + Stalk Falls Off

I dunno, is it the 24/7 lighting that's the problem? I can't test right now as I scrapped my chilli and pepper plants and started a new lot. Any advice about lighting times and or temperature would help me tons as well, as well as any kind of NPK formula I could try. When it starts to flower I add more potassium, less N, as I was under the belief that they love "K" and "N" would cause problems, but once again I've tried all sorts of amounts, and formulas, just nothing works in that area.

And finally they are insect free, humidity is around 36-50% (it does shift quite a bit)
