What signs are you seeing?
The collapse you spoke of. It's fairly common when the light is increased by a bunch. It revolves around the energy stores in the plant. The switch to bloom food may help, especially if there is high nh4 nitrogen in the grow, though that's generally a soil thing. Your problem with feeding high is the stretch you are trying to avoid. It would be better to slow things down a bit. Let the plant do better, by not wilting it.
Just while you pass the signs, then start getting the power down again
I can't help but hear my brain screaming ARABIDOPSIS THALIANA!!! but I keep doubting it, not that I am doing anything to confirm or deny my doubts, but such is life, nothing really madders.

That light meter is x3 iirc, so 800 looking up, and 1200 looking out from the sides
I thought you put a sticker on it?
You are no stranger to doing this I know. Perhaps your older leaves never grew expecting this sort of excitement. I expect you could keep them functioning with more gradual increases though. If you actually wanted to retain them, that is.
Damn that is a lot of light for such a small place. But I think that if increase your air humidity and drop the temp a bit you should be able, keeping the intensity of light to regreen your leaves. And stop actively acidifying with nutes, I tried it to, I got yellow leaves, I dunno if in your setup it would work, but I stopped giving a damn about pH and they are getting greener just with misting with tap water. I currently have no clue what my pH is.Another way that I have tried to measure my light intensity is with the LED strip specs and my current/voltage meters.
My strips are 180 lumens per watt.
I have 48 LED strips (the four ceiling strips are double length and count as 2 each).
These are my current power readings,..

So, (19.7 × 2.18) + (19.2 × 3.75) + (19.1 × 3.27) + (19.2 × 3.38) = 242.3 Watts.
(The reading from my Watt meter at the outlet includes the waste of the power supplies)
So, 242.3 × 180 is 43,614 lumens.
I have no idea what that is in PPFD or if it's even realistically applicable?
I could have all 48 strips mounted on the ceiling aiming down and I'd have the same 43,614 lumens in the closet.
I'm sure that would roast my plant from the top down.
