Bisto-- ..indeed, no DE spray-- talk about residuals! this stuff is the microscopic"skeletons" formed by single cell algae, made typicaly of what amounts to glass,... at the bugs' scale, it's like shards of glass to them, doing physical damage, best used on soil surfaces,... There are lots of food-safe/canna safe products out there, I'd stay away from all aromatic oil derived stuff because you're in bloom,... Like Astro said, it's far more effective to have two different products to hammer them with,... since you have one of my suggestions ordered as mentioned by my mate Ronin, I'd score something that has Spinosad in it,... this works on an entirely different level vs Azamax, so it's a serious 1-2 punch! Spinosad is a neurotoxin (like pyrethrum), derived from an obscure bacterium, fragg'ing their nervous system; you'll get good info on the Axamax label about how it works,... neither are
right now contact killers, instead, they sicken them badly first, stopping feeding, etc., then croak out a day or so later,... but contact must be made, and so apply a couple repeated alternating treatments... your spraying skills need to be good, getting tops and bottoms evenly and thoroughly, pot sides too,... clean-up loose debris big time as best you can, (after harvest, you'll need to go full decon'),....I like these two products because they don't leave much residue, and can be rinsed gently away down the line,... do all this during light hours, away from any direct light (save fluoro'), early on, too allow things time to soak in there and dry off... double check by lights out,... also, I strongly recommend adding a water spreader/wetting agent to all sprays; this will make treatment and rinsing more effective,... it takes the surface tension out of the water/soln. you're spraying, so it coats and sticks far better, and also help penetrate the pests' natural water repellency,... Mites are nickenamed the plant Borg for good reason!
... in some ways, they're more like a disease than a pest, and there's no one-shot cure either... it's a damn war!
