Mites thrive in these conditions:
Hot
Dry
Still
And hate these:
Cold
Humid
Breezy

You can drop your temps and apply Neem to impede their reproduction. Add air movement in the grow area. Use a dust buster to vacuum top buds, where they congregate.

Then hit the room with a couple Pyrethrin bombs, spaced a couple days apart, to kill them.

Avid is a good product but is a systemic and should not be used past week 2 of flower. Same goes for Floramite, which I personally wouldn't even consider on a crop meant for consumption. Both of these are regulated pesticides. Use a pyrethrin/neem combo first, and hang no pest strips. Also with the NPS, ventilate the room well before working in htere, and avoid using them in living areas.
