yeah, that's bud mold. Good luck with that. You can cut out the affected areas, but cut at least 2" further than the spots that you see mold. Drop you humidity, reduce watering, raise your temp, keep night temps above 70 and you might finish ok. Or go buy a sulfer vaporizer, that will kill it, but still do all those things i just listed.
People, keep your humidity down during flowering.
big thanks!!!!!!
