Alright,
First of I put urgent because a decision will be made in 48 hrs. not because this is life or death. The situation (as are most) is my own doing. We can go through the backstory and mistakes made if you want, happy to share...
Sufur vaporization / pH damage
Before the big burn (2 smaller burns done)

I had budrot on a harvested plant and the 2 ugliest (oldest too, coming up on 5 wks.) plants had the longest exposure to the vector plant. The white spots and nectotic material are what is concerning me.

Opinions? Questions?

Kinda depends. Lol
If it's not an infected leaf I just keep an eye on it. Myself I typically leave them if theres still any green to them. If the plants pulling energy from those reserves i dont want to be taking away its supply.

If it's an infected leaf I take it off right away.
Put the scope to it if I'm unsure. 100x shows what's what. Lol.

OK, so its been 2hrs and I just had to stop myself from picking up the pruners! LOL this is going to be a long 48 so here are some more photos and info on how this plane crashed.
Mistake number 436 was placing the veg plants back in a tent that had minsismal humidity control and too intense light.

Here are some updated pics of the flower area. Some of the whitish spots have begun to turn nectotic. The smaller brown spots appear to be speckels from the sulfur itself. I think this because on this longer burn nearly all of sulfur in the crucible was burned off, where in previous runs there was about 1/3 - 1/2 remaining. From what I have read I probably produced S03 instead of SO2 but obviously I am no chemist and should not be relied on heavilly for advice but I am happy to serve as an example...

This one looks like a likke combunation of the white spots goong brown and speckels , it's an older leaf on one of the younger plants.

Edit I have 60x scope not 100% confident in my id ability to say I scoped the earlier spots and was enough to push me to do the burs in the firstplace.... a 100x might get here by Wed.

What's the humidity and temps like with the lights off?

Since the cause is pretty much figured out, I figured I'd give my half a cent lol. So what I would do is take any leaf that has crumbly parts to it off. You dont want to make trimming harder by having tiny pieces of it on buds.
If it is chemical burn coupled with humidity it wont spread so the affected leaves shouldn't get worse, so take the ugly ones and keep a close eye on it.

I think you're right. I also think that means there is dew at night which is probably what is causing your problems.
I have not noticed dew but part of managment is to run the veg 3pm-10am and it sits inside the flower area that runs 8am-8pm. The lack of control on intake air definitely complicates things the diferential is often in excess of 50 deg amd rh is regular in low teens but lately has been humid. So since I am intaking outside air its a moving target to hit while on the run.

Not apples to apples, but hopefully an ample example...

I try to be as healthy as possible with my plants, and the last spray I was using to fight aphids and mildew was JMS stylet oil, at 1.5-2 TBS/gal.
3TBS/gal is supposed to be safe. (As it turned out, I just needed a good flat spraying garden hose, and more food, respectively)

These are the same plants a day apart. Bodhi's Dread Bread on the left, and Bad Dawg's Star Dragon on the right.
They did not recover to what they were. Top damage in top pic is from them overgrowing their light.
The worse stuff in the next pic is from the oil spray. If the oil concentration is too high, it seems like it coats and chokes the leaves to death within a day or two. They're oily to the touch too.
If you spray with oils, be careful with concentration...

They only got worse from here for a couple months. They kinda rebounded, and are finishing life outside in 2 gallon pots. Damn shame compared to what they should've been!
