10x10 grow room help from experts

So guys I just started a grow in my 10x10 grow room. I have a 120btu AC running. A SF4000 light partitioned in to a corner of 8x5.
I have a small humidifier running and the oscillating fan I have also acts as a humidifier as well. But I still run in to the trouble of room getting too dry and humidity levels dropping. This has really stunned my girls seedling stage. These babies in the pics are almost 2 weeks old. Some are younger.
I’m growing in a soil mix I made of :

coco
Potting mix
Compost
Bone meal
Blood meal
Vermi compost
Rice hulls
Charred rice hulls

Would love y’all opinions Thanks growers.

you should put some type of bag over the plants so the humidity can build up

also what is your PH of your water?

Is this going to be a sealed room or are you venting outside?

It is a sealed room. I’m not giving them co2 yet since I have only few plants.

I didn’t test it yet. Since I’m growing in a living soil, ph adjusts itself ehh?

definitely need to PH the water... are you using reverse osmosis, tap or well water?

Looks like you are frying your plants from too hot of a soil mix.

My guess is not the food, but the LED. Babies need to be acclimated to LED or they will burn like this. Raise light way up for a week or two. The bad ones you have likely won't recover.

Yeah a friend of mind told me too. Think I should flush it couple times? Wouldn’t that over water the seedlings too?

I raised the lights up and they reacted good. Leaves are turned up. And yeah I don’t have much hope about the small babies. Good learning curve.

Well water

Every plant in your grow can be saved. Get the light up. They dont need blazing sun right now. They need 75f to 80f temps and 70 to 80% RH. And get some ventilation in that room. Does not need to be much. Your nowhere near CO2 time or skill set. And don't kill them with over watering.

The ladies are looking a lot greener and alive. Thank you sir. Also I have a small humidifier running but the AC over powers it at dehumidifying. The RH levels stay at about 45-50. Is there anything I should do to help this?

What are your temps?

Update :
Thank you got everyone’s expertise. The ladies are doing great. Some hints on leaves though. What do y’all think?

Why are the leafs dripping wet?.... don't mist while the lights are on, you'll get burnt spots. .... Kinda like I see above.^^^^^^^^
