Looking for help with this sick plant

[Greenstarr]

This is my very first grow, from the time she got her first true leaves they were always twisted so I figured the twist must come from it's particular phenotype but it's growing a lot shorter then my other plants and you look closely there's yellow spots on the leaves and the other one with the upturned leaf tips and discoloration closer to the leaf stem I have no idea what to do with it as I seen upturned tips but idk what the discoloration is. Any help?

Hey @Greenstarr welcome to 420mag!
It could be quite a couple things. Second pic is looking like heat stress.
We'll need some more info on your grow to try and troubleshoot your problem here
What is your average tent temp? Humidity?
What light setup are you running? What's the distance between your plants and your lights?
Doing anything for ventilation?
What PH are you watering at? What nutrients are you feeding and how often?
The more info the better. It's unfortunately a bit tough to see what is going on with the blurple pics, so if you could take some pictures of the plants in normal light it will help too.
Thanks man, let's figure this out!
