Light Damage too far too early?

[Edmund.Rockwell]

Hey Forum!

Im new, i tried to make sure that im not clogging the Forum by asking stuff already discussed, forgive if i fail.

I have been struggling to find the reason behind a couple of my Lumatek Zeus being hot af, raising the temp in one of my three growspaces to 5°C more than the other two, and felt a little stupid to realize that one controller seems to be somewhat broken, still switching the correct On/Off times, but displaying that its running with 20% efficiency while in reality running full blast.
Heres where we get to my problem:
I have/had about 40 seedlings under those Lights (Lumatek Zeus pro with a whooping 1770μmol/s and 2.9μmol/J) which up until yesterday were suffering from being toasted and sweating in 33°C, but im not experienced enough to say, whether the damage is "too great".
Its a semi-comercial grow and im not really shooting for mediocre weed, so i cant afford to continue raising "ruinied" plants.
I appreciate any opinion!

Sry for the long text, but i figure the Info is relevant for people with similar problems in the future.

Looks like you've diagnosed it properly. Taco-ing, edge curl, and twisting all say too much light. Give them less light than the max they can handle and they'll improve. It takes a few days...they're not contorting because there's too much light in the moment. They're contorting because the moments add up to too much light per day (DLI).

Yea, i realised what they suffered from simply because i suffered as well when i went in there. Knowing young plants need a fraction of what an adult plant needs, i knew things were wrong. But OK, you give me hope that i didnt waste 40 quality plants.

That one leaf has me wondering though, calmag deficiency, or a more severe light Damage? Also, the Pictures cant convey, how brightgreen the new leaves are. A little more and they turn white
