AsNoriuanswered grow question 3 months ago First and second picture is infected by bud rot.
3cm of healthy up and down from infected point has to go. At least i would recomend to take loses.
Mold spreads by spores, so puting any invisible ( inside of bud ) infected part together with good into jar will make all weed infected during curing process....
Worst thing in weed growing ...
Have a good read about it and take actions.
