LED Lights for seedlings

Hi I have recently set up a indoor grow,
My seedlings are above soil and the cotyledons leaves are visible,
I am using a 120W UV light
The leaves are brown and crusty and wanted to know whether it was worth keeping the humidity high until the true leaves appear?
Thanks for your help in advance
Mind my ignorance

Need more info and ideally some pictures. What light are you using specifically? Grow medium? The more details the better.

Also I wanted to ask, at this stage I am trying to provide as much humidity to the seedling as possible. Hence why I have put a plastic bottle on top of the seedlings

pros/ cons of doing this at this stage?

Admittedly I’m not using anything fancy, it is my first time haha, I ordered the first decent one I seen online (when I should have researched first) however it seems to have the full spectrum and displays red /blue and green led lights.
I am only using multi purpose compost.
I will attach some pictures of the babies

Could be a simple fert burn. It looks as if their is soil residue on the leaf, soil has fert in it so it's logical to deduce that's the cause.

Any suggestions?
Thanks for the reply

also I haven’t used any nutes at all

It looks like the piece of film between seedling and shell. I've had this film keep the two cotyledon leaves stuck together before. Wetting the film and gently removing it was quite easy. I wouldn't be too bothered about that, but if it really bothers you, just wet it, you'll see.

120w for seedlings is overkill... Your good with a bloody table light lol
