Drooping Plant! Please help.

Hey guys.
Im a total noob here and this is my first grow. I did alot of research and know my basic problems and fixes. But this im not sure of. I have had these guys for about 3 days. baught them as clones. My room gets a bit hot while were sleeping at night. Sometimes 90-95 when i wake up in the morning but there is fresh air blowing gently on the plants as well as a circulation system taking air out as its being pushed in so there is alot of airflow. I have a 400W ballast and bulb hovering about 2 -3 feet above the plants. No signs of heat stress so far the rest of the plants are growing beautifully. New leaves look green and healthy and strong. Except for this guy.
I attached the image but not sure if it works. If It doesnt here is a screenshot.

As you can see the back one is sprouting and looking healthy and th front is completly drooping.
From the stuff that I searched I found its either Under waterring because I have been waiting 3 days after buying them to get them on my feeding schedual or its because of the size of that container and the roots are trying to grow its still in the red plastic cup Im sure it was cloned in.
What else could it be? What can I try to bring her back?
Also I want to water her now but the PH of my tap water is at around 7.5-8 Which is too high for soil. Is it okay to feed her this until I get PH Down and some nutrients? Or should I just wait and get the PH Down and nutrients first?

Answer what you can. Please try to help me bring her back.

Thanks

Gotta get those temps down. I had heating issues, but im just going from seedlings. I'd honestly say if you can go get nutes and ph down and maybe leave your tent cracked to keep those temps below 90 your plant should get happy again . Im a noob but just going off of experience so far! Hope this helps

It sounds like a sick ,weak one. Let it go it should recover and reduce watering.

With the temps ,healthy veg plants can handle higher temps 80-90. Seedlings and flowering plants need temps 70-80.

I watered them for the first time Got my PH to about 7 which is still a little high. Going to get Nutes today and give them a little spray with some nute water.
I have them on Boxes to get a bit closer to the light. Should I take them off of the boxes that may reduce light but it will also greatyly reduce the heat problem.
What do you guys think of the pot being too small? Should I change the pots they are in currently?

I have 1000w about 3 foot from the seedlings and they are doing fine so far. Just a simple hand test will suffice. If its too hot for your hand its too hot for the plants try and keep a fan blowing the heat from the tops if you think it is too hot. Also would it be possible to take the ballast and put it on the outside of your tent? Those seem to generate alot of heat too.

I watered them all just basic water with a 6.8PH the main problem one it perked back up by the time I turned my lights back on the others are sort of showing the same signs but the water is improving. They just got dry and thirsty. Going to spray them with water mixed with big bloom just to get their nutes back up.
STILL OPEN TO SUGGESTIONS!
So dont mind keep posting.

Thanks everyone.
