Buds changing color HELP

It looks like the start of bud rot, you want to remove it ,cut it out before its spreads. Its not your lights because the leaves are not showing signs of heat stress.

Give her a sleep period of at least 4 hours & move your light further away. She is a light feeder, so less if more.

Looks like the light is too close causing light stress/burn, and too warm. I don't see a pollen sac. Which is a dick thing to say if you don't actually see one. Not sure how big a light you are using, but they need some distance between the tops and the leds. 👍🏻🌱

Look like a light burn move the light away from the buds download the PPFD meter app so u can fix it better

could be light burn. looks likea pollen sac in one of them. the pics ar ea bit too far away/blurry to be certain. budrot would have some fuzz underneath. the sugar leaves would also be dead. if it looks like singed pistils, raise the light 3-4" and see how that goes. they are lil yellow nubs initially with light damage.. bleaching occurs later on in progression
