Don't add any sulphur in conjunction with or after any sprays using oils, the two together create a phytotoxic effect on your plants. I'm also not a fan of OG Biowar as I personally think it is a vastly overpriced product where %70 of the product itself is Talc.
I had recent success against Russet Mites by using Green Cleaner for 2 or 3 applications, 3 days apart to initially knock them their numbers down. Apply the predator mites several days after your last green cleaner application so that they won't be killed off by it before they can do what they are supposed to do. I would order predator mites right now and get them to you before any additional damage is done. The nice thing about the mites is that they will stick around if cared for and will continually do work against spider, russet, and broad mites. I ordered mine from Evergreen Growers Supply. Here is a link where they break down what good mites will combat the bad, specifically for cannabis. http://www.evergreengrowers.com/crop-recommendations/cannabis-crop-recommendation/medical-marijuana-crop-recommendations.html
Here are the relevant ones for you that I had on my last order that I was very happy with,
Amblyseius swirskii - For Russets, Broads
Hypoaspis (Stratiolaelaps scimitus Womersley) - General soil mite, good defender against fungus gnats, etc.
Amblyseius fallacis on bean leaves - Good attacker against spider mites and good general defense
Amblyseius cucumeris Rapid Release - Also eats russet mites and good defense.
Seafour also recently recommended to me to get bee pollen to apply to the plants after a time so that they can feed off of it after bad mite populations begin to dwindle and the good mites can eat that as well as the bad mites to survive.
With all of this you can create the perfect defense to really knock them out and also keep them around so they don't stick around. I would venture a guess that if Russets are around then they are all over so you want to create this good environment for the beneficial predators to exist and stick around to perpetually keep the Russets off your plants. Keep us posted, no need to lose sleep
Regarding the OG Bio War. From what smart/somewhat experienced people have told me about that product isn't good. I don't use it, or recommend it. However, if you have russets or broad mite during flower, it tests clean and knocks down the populations. I used double recommend amount.
