I know someone whose grow was wiped out by offgassing insulation. I hope you can get your issues sorted out.
Hello!
I had the following problem... I grow using the KISS method.
Substrate is pure perlite. PH and EC is fine.
In my veg room all is fine.
But in my flowering rooms I had some leaf issue. Looks like Mg or K def, or both, but in the fact rising the levels of this elements doesn't change anything.
I also have some spyder mites, and fight with theys about 2 month... they still not totally killed.
So most intensive problem I can observe in more bright and sweet spot under HPS lamps.
I suspect offgassing... because I put on the floor the cheap linoleum. and I'm using some PVC pipes to drain and irrigations.
Please help me define the problem, nutes or environment.
So some pisc of problem in different stages:

It's NOT caused from off gassing.
You are dealing with hot spots.
Raise the lamps, increase air flow at top of canopy and move plants away from hot-spot immediately under the lamps.
Oh and get them bugs under control.
