regular rubbing alcohol from the pharmacy works fine, mix 50/50 with water and spray over and under leaves

Have you thought about using predatory mites? It’s certainly more expensive, and slower, compared to a bottle of rubbing alcohol. But they do work and they did rid me of the thrips problem I had. Works on Spider mites as well.

I got my predatory mites from Amazon (seller was Nature's Good Guys); they are shipped live (chilled), so you should be home to accept delivery. I think they can be used in any grow mix; they die off naturally when there's no more prey. Worked wonders on one of my girls that was too bushy to try foliar treatment. Best applied before the pest has gotten a solid foothold.

I’m in Canada. I used https://www.thebuglady.ca/ for my predatory mites. Only downside is that their smallest product size is for 1000sf of canopy (for their bugs for thrips). The last time I talked to the company I suggested they come up with a much smaller package size and target the small growers in the cannabis market.
One product gets sprinkled on the leaves, the 2nd product was sprinkled around the base of the plant. I left the foliage sprinkled like a birthday cake for 2 days, then used my compressor to blow all the debris off the plants, followed by a good vacuuming of the tent.
