Are you using any nutes? If you are, then stop immediately and don't use until the plant is about 1 month old. Just make sure that the heat isn't too much for the plant. Put your hand to the top of the plant and make an assumption if the heat is too much. If it's too hot for you, it's too hot for the plants. As for lighting output, you can never have too much light. Good luck!!

i'm only using half the amount right now. i'm using earth juice grow and fox farms big bloom. all of the other plants that are in the hydro are doing great thats why i think its the heat

Rootbastic kills heat

I think that maybe its not getting enough nutrients its kinda tall and the leaves arnt really busy, maybe you should give it just a little bit more light.
