Thrip control?

I put water in a spray bottle with a few drops of Dawn dish soap when I had a similar pest problem, but that happened to me during veg. Maybe if you did it extremely, extremely lightly and try to avoid the buds, but I honestly wouldn't recommend spraying the plants with anything if they've already flowered. If it isn't too bad, I would try and wait to see it through to the end, but if things take a turn for the worst, be ready to chop her down early and save what you can. I'd probably remove any damaged fan leaves, as well. Sorry to hear about the bugs this close to the finish line. Hope this helps. Cheers!
