Is this blackjack autoflower bud rot ??

Help!! blackJack autoflower's color is usually darker than any other cannabis but it seems to be something wrong with my blackjack.
By looking at the pic, Is this bud rot? Bud color is dark brown and leaf turned a purple.
If it is, is still smokeable?? or should i throw them out??
Please let me know.. It took me 3 month for that bud and it will be very helpful if you could answer my question.
Thank you all!! Have a good smoke not like me!!!

Yep. Looks like botrytis .. my plants last year got hit with it.. I turns the buds into kinda a pinkish color. Kinda slimy.. but the giveaway is the fan leaf that all of a sudden dies and looks like your pic.. it's devastatingly quick too.. do not smoke that shit!
