I think it's damage caused by the larvae of some kind of moth, or some other pest....it's not mold...yet...but as soon as some rain falls, or it get's wet, it's gonna start to rot...you can try to remove the dead, brown parts, or take off the whole bud if there is no other way...
But of course it's not 100%....you should wait for Stinky....

btw....the plant looks really good.....nice work Sky....:thumbsup:
