Advice needed please

My first real indoor solo grow. Bought some real good genetic clones but now have russets. I see no way of getting rid of them without crazy chemicals or just burning the plants and bleaching and starting over. So please advise, here's my thoughts. 5 plants 2 showed russets bad so I put em outside. The other 3 are beautiful plants but showing signs too now. Do I just try to flower anyway and see what happens? Toss em get seeds and start over? Leave em outside to flower naturally anyways? Also I have seedings in The same area should I toss them too or move em away and hope they don't have em too? Stressed I've spent so much money just to grow my own and stop spending money for this to happen

I had russets last year for the first time ever and they were much worse than spider mites. I didn't save any clones. Flowered the plants and sprayed neem until buds formed. Cold weather below 55 slows them but personally I would
-Treat (spray) the seedlings and anything that's not affected.
-All contaminated material would be disposed of far away from the grow area and I would sterilize the whole grow room and lights etc then wash your clothes and take a shower.
Sounds crazy, but it's that kind of measure or continue paying more and more to try to get rid of them. Sorry, friend! From now on, you should consider an integrated pest management plan. I spray pure neem oil or other safe products weekly in veg as a preventative action. This way, I will not allow new pests a chance in my grow. Good luck!

^ Zero tolerance. Id be steri the room and house too. But thats me im old and over cautious
