AVID combined with Dr. Bronner Peppermint Soap works great. If you're in Cali you can get Abamectin shipped to you which is the active ingredient in AVID but for some reason is still legal. M-Pede works good just to keep things rotating, you can pick up 2.5 gal of that stuff for 90 bucks, it's safer than AVID, you can use it during flowering, and your plants LOVE it!
Nuke 'Em works alright, but it doesn't work quickly. Big Time Exterminator is caca in my opinion as a foliar spray, I swear to god the red mites must have thought it was an aphrodisiac because they just got worse and worse the more I used it as a spray (yes I know to rotate pesticides and spray every 3-4 days with mite issues.) Russet Mites just take time to get rid of, they are very strong and resilient.
If you aren't already flowering and the damage isn't too bad, you can spray with 70% isopropyl and that kills every bug and all their eggs. If you already have a bit of damage on the leaves it will make them worse though. Plants that are relatively blemish free don't seem to notice anything happened. I say don't spray during flower because you'll probably dissolve your trichomes.
With products like AVID, Forbid, Hexagon, Pylar, and the like, it is SO VERY VERY FUCKING IMPORTANT TO WEAR A FULL FACE MASK WITH PROPER CARTRIDGES. I've once been bed ridden for weeks on the verge of death because of spraying AVID indoors with a half-face mask with improper cartridges that were used for more than 6 hours already. If your cartridges are more than 6 hours old, throw them the fuck away like you're angry with them. Do not ever try to use one of these products with a half-mask and goggles, the mist will settle on the bridge of your nose and forehead, and all it needs to do is soak into your skin near your sinuses to massively fuck up and put you in the hospital.
Do not ever attempt to spray a solvent like isopropyl with a mask that has pesticide filtering cartridges on it, it will not help you. You need cartridges specifically made for solvents.
You will probably not find any of these cartridges at Home Depot, Lowes, or ACE, your best bet is to go online.

If it isn't NIOSH approved, you're putting your health at risk. A good friend of mine spent a very long stay in the Hospital because of this stuff and the doc said the inside of his lungs are toast and any respiratory infection for him will be potentially life threatening, he also runs out of breath really fast, so now he can hardly even pull enough air through a respirator mask. I was lucky that I was just bed ridden and didn't end up that bad. But I never went to the doctor because as soon as they find out what you sprayed, they report you to some government agriculture agency and they tried to fine my buddy thousands and thousands of dollars, he had to make up some BS story about his mom's farm in Pomona, which is actually a farm, not a pot farm, and she is licensed to have that shit.
A full body suit is also an absolute must. It can be a rain coat/pants, but it must be washed in a heavy bleach or hydrogen peroxide solution BY ITSELF, and NOT IN YOUR REGULAR WASHING MACHINE, after every single use NO EXCEPTIONS EVER. Which is why I recommend a moisture resistant, or even splash resistant disposable suite w/ hood and booties, they are as little as 5 dollars a suit online, and god damned worth it.
You may think I'm being way to particular about this, maybe a little OCD, but that may be because you have never experienced the absolute horror of being poisoned by this shit.
As long as you take proper precautions, I can tell you that you will be safe using these products, but to not use the proper equipment is silly. I got away with it a few times, it wasn't until I used it heavily indoors that I got poisoned, but why would you risk it?
It's important to shower immediately after spraying, even if you don't think you got any on you, for at least 20 minutes.
THERE IS NO ANTIDOTE FOR AVID POISONING, YOU EITHER TOUGH IT OUT OR DIE.
I recommend using a atomizer to spray your plants with or a paint gun with an air compressor so you can get the job done as quickly as possible while keeping the spray as far in front of you as possible. This way you wont have to fuck around trying to spray under every leaf.
