First Grow, 2 Critical Purple,1 THC Bomb

Another week of thinking my plants are done. They decided to add more onto the canopy as I was thinking they were getting too hot. I raised the light and they grew more. I am concerned with the curling of the leaves being heat, then nutrient excess or deficiency to a possible lock out. Other than the leaves freaking out on one plant they seem to be healthy and constantly bulking up.
