Looks like heat or light stress. What are your temps and how far above the canopy is your light? How many true watts from your light?

get yourself one of those cheap infrared temp guns, check the leaf temps under the light.. if the room is 30 C degrees.. what is that, 85 F? The temp of the leaves under the light are going to be higher. They will taco under heat stress, especially in a lower humidity environment.

okay i actually have one so im gonna go do that now thank you ill be back in a few mins with the readings
 
In a 4x8 tent you should be aiming for at least 1120 watts of quality LED light or 1600 watts of the kind you're running.
35w per square foot of good LED light or 50w per square foot of lesser quality lights.
