I checked about 50 leaves from various plants, most from the DWC. I pulled the leaf off and looked at it under the scope. I saw nothing in the DWC plants, and nothing on the new Early Miss and the THC Bomb. I actually checked every leaf on the last two without pulling them off.
The mother plant is of course still infected, the poor little runt is as well, though not anything like the mother plant. It needs another 2-3 weeks before harvest, and based on what I've been reading I should be able to manage that. She stays outside, though.

I brought the second Early Miss back in, since I'm convinced it's clean. I'll check it once a day for 3-4 weeks. It's sort of my canary in the weed mine. If it gets infected, I'll know my mite problems are just beginning.
Next I did the only thing anyone on youtube claimed resulted in a mite free plant, I hit it with high pressure water under the leaves. I will repeat that every day for a week, then switch to soap or neem oil. The thing looked pretty haggard afterward, but it was fine an hour later. I checked another 10 leaves after it was dry, and found no web, eggs or mites.
I had some clones cooking in a seedling tray, and was thinking I might get lucky and find them without mites, but they were even worse off than the mother. I tossed the tray and all, then hit every surface with Simple Green.
I then got up the nerve to open the tent armed with a shop vac. I vacuumed and disinfected everything, then rotated the light so I could hit the DWC plants from the side. I also disinfected the area around the intake vent where the mother plant had been sitting and turned the fans back on. I will be checking the DWC plants daily as well. There are at least 4 weeks before chop day. I hope I can keep them reasonably clear that long.
