Please help!!!

This is my third time growing plants and I never had this problem.
Can anyone please tell what's wrong? and how to fix this?
PLEASE!!!
THANK YOU!

Give those poor things a drink

either under water or over water mabe heat as well....

if this is for real u should give up on growing anything

Water enough until you see water coming out of the bottom of the containers.

You'll be surprised how fast they come back.

That looks like aluminum foil you're using to cover the walls and floor of your grow box. Get rid of it. Aluminum foil causes heat spots that will dry your plants to hell. I've had heat problems in the past, and although it has never gotten as bad as yours seems to have become, it will cause your leaves to droop badly. Without immediate intervention this heat stress will kill your plants, especially if you don't have proper ventilation. Use mylar instead of aluminum foil or even flat white paint. As mentioned above, over or under watering will also cause leaves to droop, but this to me appears to be more heat related. What are your temps at? It's important to keep your roots cool at all times. Also, fill up your pots to the rim with soil. This will help to insulate them from the heat.

Thanks all! the temp is about 32℃ i just removed all foils. Is there anything else suppose to do?

those plants are not over watered they are not watered at all . they are dryer than a woman in a coma's vagina . if its a problem more than once transplant them to a bigger pot dude . over watered plants leaves curl down but they would never wilt like that. high temps cause a plant to use way more water so look into that as well . damn dude lol
