Help !

zoom on those weird colored buds please, they look like budrott and if thats the case i would harvest and seperate the mold instantly, looks very spread in the 2nd picture on the right bottom side

Not burned, but suffering death due to bud rot. Cut the dead buds off very carefully, get your humidity down as low as possible and pray the rest doe not get rot too. Sadly, you will obviously lose quite some yield. It has happened or will happen to everyone that grows, sooner or later, and can be heart breaking.

Also if it is rot, remove that plant if it has not yet contaminated its neighbors. you can still try to salvage it and cut out the rot.. but if possible finish it outside or a different tent. do clean thoroughly after any infection.

Maybe, or there is some bud rot under those buds... the sugar leaves are all dead too, so, take a peak and look for white or grey fuzz festering underneath. If so, throw out large portions.. cut liberally aroundit. the spores are already all over everything, lol. if it is rot underneath, it's possibly shit smoke even the visibly clean buds. I hope it is the light. if itis the light i use the little mesh bags for protecting fruits from frost but still breathable. I put those on top of taller colas that are expereincing light bleaching to attenuate the light intensity without creating a high RH% local enviornment ripe for mold. Anayway, attenuating the light on a few colas is better than turning down the power which affects all colas and reduces penetration of light signifcantly. High RH for extended periods of time are dangerous. i hope you don't have bud rot.

Those top buds that went crispy are experiencing bud rot. All I can suggest is to get a dehumidifier and try to control your RH.
