Bad Heat Stress! <-- HELP!

Hello,

I am using hydroponics and successfully grew 3" tall healthy plants from seed. However, I attempted to use my grow box last night for the first time and I cooked my plants, literally! When I opened my "light tight" box, heat came pooring out -- it was about 110 degress! As you can see from the pictures, 80% of the leaves are damaged. The roots and stems look very healthy. I have seen plants come back damage in the past (when I first started with soil).

What is the best way to help bring these plants back to health? There nute levels are at 900 PPM. Should I wait 24/48 hours and remove the worst of the damage? Should I remove damaged stuff now? Should I cut the lights back? Should I lower the nute levels? How about a specific nute to add (like for transplanting)? Any suggestions?

Thanks!

a couple of fans blowing across the tops should help . with some fresh air coming in as well.

Okay, but should I remove the damaged parts? Should I reduce lights? Decrease PPM (nutes)?

I've removed the plants from the box until I can make improvements to it. I will put a fan in the plant area. Anything else? Thanks

Bummer man, they look like hell.
I think you should remove the damaged foliage no point having the plants trying to fix shit that not worth it.
My only concern is that once you remove the damaged shit will there be anything left?
Also 900ppm seems way high for such small plants so pull back to 350 - 400.
Were they at 900ppm and growing well before you cooked them?

leave the damaged parts till they recover.

raise the lights a bit.

reduse the amount of lights.

reduse nutes. and get a fan on the go.

I did the same thing with a faulty space heater that just fucking melted one side of a fem...it's fucking disappointing. But the one side is growing healthy it fried the two tops where i pruned it. It is starting to re coup though,
