bleaching or beginning of bud rot? Please help`

Purple Haze 41 days flowering out of 56 it normally gets before chop. I think it's bleaching and i cracked the bud open and it seems pretty green. The tips of the bud have a little grayish look to them too but I don't know. I'll chop them down if need be. What do you think? Any questions let me know. They're in coco. 3 x 600watts. 4 x 8

What is your humidity running? To be safe you can cut that white part off so you don't worry it spreads. Was that plant super close to light? When you rub it does it disintegrate or is it like normal bud texture?

If you pull on the leaves with the brown gently and they come out easy, you have bud rot.
