Its most probably something to do with the light.
1. what sort of light you are using?
2. how close is your light to the plants?
3. What light cycle are you using?
If you post this in plant problems you wil get more of a response

I'm using hps 250 watt i have them on 18/4, There only going 2 weeks so i haven't given them any nutrients just super thrive, i have brought the light up a bit more and moved the fan, i'm freaked cause its my first grow

I guess you mean 18/6 light
And how many inches away is your light because hps lights get very hot and normaly if the leaves are curling upwards it has somthing to do with the light.

Superthrive is a nutrient. How much did you use? Nitrogen overdose. Also what is the soil? Pre-fertilized soils count as feeding. Moving to grow where this belongs. Welcome.
