dude, these are not pests to ignore! At this point you have a full generations cycle going, meaning they're established in plant and soil; they undergo a sort of pupation there, not feeding, but emerge as adults--which can fly BTW! They black glop is their shite, and they can create bio-debris of their molts, eggs, and dead that will contaminate your buds!
... there are foliar spray products you can use during bloom that leave little residues behind: pyrethrum and something with Spinosad in it,.... both are very effective on thrips, and are food safe pesti's! Pyrethrum is derived from chrysanthemums, and spinosad is derived from an obscure bacterium,...both are neurotoxins!
They don't kill right away on contact, but they sicken quickly and go off feed, dying a day or so later,... if you want to war on them, let me know and i'll go into more detail,....
