Plant leaves looking really sad

hy guys. I saw some indoor plant , with leave illnesses. I have never seen a problem like this before.
Can anyone help me about the problem . Unfortunately the inner temperature in the grow tent is around 100Fahrenheit daytime(around 35 celsius). In the night time 85 fahrenheit ( 30 celsius). The girls are growing under 60 w of CFL ( 7000 kelvin ) . And they are 2 weeks old. Quarter unit of high N nutrition once a week. Not overwatered. 4-8 cm (2 inch ) from lightsource. There are some pic

You need to get your temps down. do you have a fan on them?

Yes i have a light fan on them, but i have high co2 level , and i heard warmer temperature is good for them in high co2. It doesnt look like sunburn or too much heat , that is why i dont know what to do.

I think maybe 35 is a bit too hot regardless of co2
If you can, try to lower the temp several degrees
An easy trick that takes off a couple degrees is to put an ice brick in with the plants in a bowl
It will melt, so you have to have two or three and constantly change them out and refreeze the melted one
Temporary because it's annoying but it can be useful

What is up with your dirt? Looks like straight soil maybe needing some aeration. Lack of O2 in the root zone will make your plants look overwatered even if they are not.

If you want to fix what Bugeye is talking about, which is quite likely
You may want to transplant into a bigger pot willed with the same soil but with added perlite
Perlite is white rocks, it's really cheap and available at hydro stores
I got 25L for $7
Say if you had a 15L pot, you'd want to have about 4-6L of perlite mixed in with your soil
It provides aeration and holds onto water a little bit
