I was having phantom issues in my sealed room,started doing an air exchange 4 times a day and plants started to jump.
I see your using blurple lights so I doubt you would see any difference until you switch to a better led.cobs or quantum boards.
My flower room is basically like yours with a mini split all sealed up.ill pull around 5 to 6 lbs on the left 4x10 and around 3 on the right

I know this is old but I have a very sealed room 24x30ft and having some major drooping problem I turned my burner off and after a few days plants look great. Try running co2 at 500 ppm they go droopy again if anyone can help out it would be appreciated
