ruined

First time defoliating heavy, I got carried away and pulled wrong leaves improperly. Have I ruined my harvest ?

i hung a bud in a shoe box in my closet to dry and in about 2-3 days it has started to turn black. Not sure why this is, but I'm concerned it may be mold. Though i have read that this can be caused be deteriorating choloraphyl, which would make sense because it was trimmed fresh. Has anyone else...
