imo - if you are hitting the plant with something, try pyrethrum 5ec (you can also drench the root zone).
Two or three applications (over a week) does the trick. Residues are minimal and disappear in a short space of time.

A trick in flower stage; with light driven strains (not autos). you can drop the light cycle below 12hrs (say, 10 hrs). Mites usually stop breeding below 12 hours, so will all/mostly die off in a week or so.

*edit*
adding diatomaceous earth (from the start) to the soil helps. A layer on top of the soil is good too (sand could be used on top of the soil also).
Sprinkling a thin layer of diatomaceous earth on the floor around your plants (better suited to tents) helps out as well

Can you use pool grade diatomaceous earth or does it have to be food grade?

Any brand of soil can potentially have some kind of pest with it. It's not just a Fox Farm thing.
ain't that the truth.
if i remember correct mine came from Gaia green living soil in bags....was my first foray into actual organics not that bottled pure blend "organic" fertilizer crap.
I hate the gnats.....but i haven't touched a bottle of any nute since and its so much nicer to just water only
