If you decide to fight the mites, then pyrethrin based products might be an option to rotate with neem oil. I would also remove the heavily infested leaves and throw them in the trash outside or even burn them if possible. Then disinfect your room after the current run as spraying can probably only control the infestation and not totally eradicate it.
Thanks
I've decided to get rid of most of the biomass in this grow
Just way too much to think I can eradicate them ( plant matter and mites )
I'm going to start with a donor plant that is mission critical to me, and would be only thing I think is necessary to me.
I will take cuttings, and submerge them fully in a pH balanced solution of kelp extract and Neem oil.
I'll put an airline in there, and keep them underwater at least 30 mins, before rooting them.
If that works ( they survive the swim ) I'll cull the donors.
I have another strain that I might just abandon, or soak out and then just keep cuts.
This current grow is just presexing.
I'll leave it another week, to sex out, but probably remove most fan leaves.
Cull all males.
Cut and soak female cuts in drench.
Remove everything except the cuttings.
In two weeks when the cuts are rooted, give them four full drenches
A lot easier to handle the plants as cuts, also a lot easier for me to spray them fully, and not miss anywhere.
I'll use pyrethrum, Neem, methylated spirits dilute ( alcohol ) a garlic+rosemary ( to kill eggs ) and also a soap, in combination over the four sprays.
Sprayed on day 1,4,7,10 out of the igloo.
I think this should get rid of them.
Other than that, I will have to abandon pretty well everything, and just keep two or three cuts of my most precious donor, and rebuild from there.
