Hi My plants are big bang, 9 days old from first popping thru the soil they seemed to be growing fine but a few days ago the leaves started cupping badly and i have no idea why and i have never seen it before. I need some help in fixing the problem any advice would be appreciated thanks in advance

In my own experience, not only will hi temps/too intense light cause that, but your humidity being too low will, too. Combine low humidity with hi temps, definitely will taco your leaves!
 
If your grow room or tent is near a window you could run some ducting from the window blowing the cold air on your lights a mate of mine had this set up and he never had a heat issue

Yep am getting things in control just about am under 30c now and plants are perking up even the canoe leaves one.
I do have a window right next to grow tent, so am considering an inline fan/ducting from the window.
I've also raised my lights a fair amount and I think that has made a difference.
