Jung seedlings are in danger..

Hi, I made a mistake the last Day's was very warm outside and u put my Seedlings in my greenhouse but forget to open the door a litte so the heat was to much I think and days later they looking weak as shit. Normally the seedings reaching to the light but they don't do it just a litte bit they looking light Green with litte yellow and some rost points.

I don't think they deficiency i give cal/mag and base nutes just i do normal it's not my first grow.



Do you guys think they recovering?
