D8-- no shit, that black crap was sap?? what a weird color,.. I've seen lots of weep-drops, usually a sugary sap, and dark red-amber,.. maybe when fully dry, the turn a deep shade like that,... good news in any case! ..... Spinosad does break down after several days, as does pyrethrum,.... if you're a good shot, you can spray carefully just the fans to reduce exposure to the buds,... thrips want no part of that,.. only bud worms seem to be able to eat the actual bud,... other bugs are just bio-contamination,... there's a method for washing bud, u-tube it,... Heavily Medicated waged an epic war on monster budding plants, and won, with fine product at the end,.. your situation is much much less severe!
