The super white parts on the tops of the buds is light bleaching. Your led lights are too close, LEDs run cooler so it’s not hot enough to burn the leaves or cause any signs of light burn, however light bleaching will degrade THC and although it looks neat leave you with a less potent smoke. I’d suggest raising your lights or super cropping and bending the top nodes down if your lights are as high as they can go.
