Predator mites - Swirskis or Andersoni's. Maybe Green Lace Wing Larvae

HydroGardens also sells swirskis, andersonis, Bioworks Botanigard Maxx (BM). BM is accepted for use by state of Colorado for Rec grows.
I personally like Forbid 4F and so does Dr. Who who posts on these forums and he knows the chemistry better than I do. Avid and Floramite? No. I think Forbid is okay.
Alternatives - don't dick around because Russets mites will essentially destroy your plants fast.
1. Big Time Exterminator (BTE) or Nuke Em. Can be used up to day of Flower.
Both indicate that they will kill Russet mites. I believe the main ingredient in both is Citric Acid and active yeast cultures. You can get them online or at any grow store. About $40 a quart. The guy at BTW says spray with ice water first.
2. Bronner's Peppermint Soap which is mainly oils. I would add a drop or two of Dawn soap or Ivory dish soap. If you have essential oils like peppermint, rosemary lavender, lemongrass, cedarwood or Cinnamon
- put drops of those in there.
3. Fels Naptha Soap - $1 at Wal Mart or grocery store on detergent aisle.

4. Essential oils - the big 4 are Lavender, Rosemary, peppermint or cinnamon.
$4.87 for 1 oz at Wal Mart. Piping Rock has deals online. Lavender is probably the first choice. Probably 10 drops per 1/2 gallon of water.
Spray under the leaves with lights off.
More things where a guy is using Lavender Bronners and Neem oil. It you have Neem oil, you can add it to 2,3,4 above.
PS: I speak from recent experience fighting Russet Mites. I used combos of all of the above and Forbid but no predator mites because usually you do not have time. You usually have introduce predator mites before you have a problem.
This guy uses 2 ozs of Rosemary oil, some Neem oil, a few drops of Dawn and water. Note this is for spider mites.
Canola oil. I have sued this with spider mites. He uses a cup a gallon. I used about 4 table spoons and a few drops of Dawn soap in a gallon of water.
And no the canola oil will not clog the leaf stomata.
