Beta I know you're trying to help and I honestly appreciate it man, thanks bud. Perhaps you haven't read the entire thread? It is getting long now lol.
My co2 generator was hooked up to my co2 meter/controller and set at 1500ppm(and doing as much). 2 and a half weeks ago I unplugged it because it was mentioned in this thread that 1500ppm might be too much(toxicity).
Now you're suggesting that it doesn't have enough(deficient). If the problem was either one of those things I'd at least see different symptoms in the plants themselves.
It's not co2.
Multiple people (including myself) have mentioned they have trouble with propane C02 burners - They emit ethylene, which builds up and displaces C02.
PLEASE consider the possibility that your C02 gen was malfunctioning, which is very common. If it was malfunctioning (rather than C02 being toxicly high, which 1500ppm is not), then your plants could not breathe and they still can't.
