So near to harvest i just wont spray anything but plain water onto the plants, to get rid of those lil foggers. The good thing is, your plants are close to harvest. So i would just let them be where they are. If you harvest, cut your plant in branches, those branches put in cold water and soda (Natronbicarbonate). let the branches for 30 mins in the sodawater then the bugs are dead and your weed is fresh and very good to trim. I wash all my outdoors in bakingsoda( natronbicarbonate). Branchesa re better to trim, and the weed dries faster ( it dehydrates) so keep us informed
