Don't harvest early and definitely DO NOT spray your plants with ANYTHING.
Yellow sticky traps are your best option.
Buds still look 2-3 weeks away from harvest.
Otherwise, ignore the thrips, they only suck sap from the leaves and should not go near the buds............not ideal, but probably your safest option.
At this stage, a thrips "attack" won't affect growth, you are at the maturation stage, so the thrips will have minimal impact on the final ripening process.
