DrJynx86answered grow question 4 years ago If you cannot see the red spider mites or other bugs/pests, then I wouldn't do much at this stage.
If you spray now, the risk of bud rot and mold (among others pests) will be far worse.
You can keep them controlled by using a tiny brush (like the ones for make up) and carefully killing them leave by leave, but again, it's not worth it as they won't do much damage so close to harvesting.
Happy smokes!
