Dude, get yourself a spinosad product, like Captain Jack's Deadbug Brew, by Bonide, and spray your plants down good. Its the best stuff for bugs of almost any kind including mites. Its a biological control, as its bacterium in solution that colonize your plants, and when anything tries to eat it, they eat that bacteria too, and die from it.
The stuff works wonders, incredibly effective, not smelly or nasty, almost like spraying your plants with water. You can spray all the way up til harvest, and no residue is left behind either.
If you do buy some, you have the choice between a ready to use liter of it that costs about $9-10, or you can get the bottle of concentrate, the small one i just got was $19, and I can make 32 liters from it. So, Id go with the concentrate. Great shelf life too. Works, wonders, I highly endorse this product.
That'd be my reccomendation.
Im an organic grower, and I try to use biological controls, and microbes to my advantage al I can. By making some killer compost teas and colonizing your roots and plant with microbes that are neneficial to it, you first get better growth, but also more protection from any invading pest or pathogen.
I also use GH Pyrolsol to add plenty of silicate and trace elemets, also make sure I plenty CA, Mg, K, Fe, etc. All these strenghtn your plant and make everthing better. It makes it harder for the bugs or spores to get into in the first place, then has an army of microbes waiting to fight anything off that tries coming in.
It like comparing a fortress with an army behind it, to a single unarmed person in the middle of an open field.
Between strenghtening your plant and colonizing with microbes, you get the best of both worls, your plants will be more lush, healthier, and more resistant to everything. ANY stress, invader, etc.
Just trying to get it across. Hope everything works out for you man.
-peace
