Dude you're 8 weeks into flower, you buds are already fucked, turn it into oil or something unless you enjoy smoking gnats or have no moral conscience and donate it to dumb asses that don't inspect the buds. Harvest and get rid of soil ASAP, clean yo shit and if you have anything in another room in veg I'd use Azamax as a soil drench and wait a week or so before moving anything into flower, Gnats I believe have less than a week life expectancy, just gotta kill off the larvae in the soil.
