Whats wrong with this plant? (pics)

I have started my first grow and right now i am a little more then a week into it. I am growing 3 plants inside a box with 2 cfls and a flouresent grow light. Is it normal for my plants to look like this? I have a feeling that the problem might be the heat inside the box which can get up to the 90s but idk. I have 2 computer fans in the box, one for exhaust and one for intake but it still gets quite hot. Thanks to anyone who posts

yeah they look a little heat stressed. try to get the temps down if possible. other than that they look healthy. g/l

overwatered.you can tell by the stems.they should not be red or pink.the stems are the plants veins for the leaves and if they are red or pink that indicates they are waterlogged.this causes a weak stem and a floppy plant because the stem is to heavy with water.you want the stems green and healthy.easy on the water untill you see the change in stem colour.i have done this before even though i was pre warned.
i learned from my mistake and seen the difference.(trust me).

LUDA.

i impoved my intake and exhaust fans so the temp should be lower and ill cut back on the water. thanks for the help. should my plant recover alright?

IMO, I wouldn't be worried about anything at this point - they are still too young. They don't look that bad. But I would definitely get those temps down! Anything over 85 and growth slows drastically. Anything over 91 for too long - without proper c02 levels - your plants will die.

yes just let it dry out for a while.you will see the colour change.

RIP, i think i just lost my 3 seedlings. i got the temp down but i think it was too little too late. I think it was the temp that killed them. I also changed from a 24 hour light cycle to a 18/7 cycle to get temps down. could a change in light kill my plants. they all look pretty similar to this.... but thanks for trying to help me guys i appreciate it

Keep the temperature down because it looks like it has a little burn but are you giving it any Nutes?.

heat stress or overwatering, maybe both and place it in bigger pot.

i was going to transfer it once it got a little bigger. and no i wasnt using any nutes. should i have? my goal was to flower them once they hit 1 foot, how big a pot should i use so that i dont have to transfer them next time?

no nutes, were you using mg soil?

thats what i thought, i was using organic potting soil
