OH CRAP!!
Yeah, w'appened dood? did you not see the Bud Rot starting? i mean once you discover you have Rot its usually too late but early enough to chop it and stop the Rot getting to the Whole plant
Damn, i had (first time) bud rot in my dense heavy Colas last run due to not enough ventalation and High Humidity but i did catch it once it showed because i was checking daily.. that allowed me to cut off the Rot and continue with growing the lower Half of the plant.
Sux man, you can zap it quick in the micro to dry and stop anymore mold advancing but still even trynna smoke that shiz is gonna be unhealthy. trim off ALL the mold affected areas and then microwave/dry the rest and make some water hash from the saved Trichromes.
