I hate to break it to you, but you might lose your entire grow.
During flowering, spider mite (and other bugs) populations skyrocket. Under 12/12 the plants think winter's a-comin and so do the bugs. Their main goal is to eat and reproduce as much as possible to be able to lay lots of eggs to last til next spring.
If you spray insecticides on flowering plants you'll end up smoking that insecticide AND lots and lots of dead bugs and their eggs.
If I were you I'd put the plants back into veg and attack the pests with at least 2 kinds of insecticide, like neem oil and pyrethium for example. Keep this up for 2 weeks AT LEAST. Get rid of 'em BEFORE you flower them.
And keep your growrrom spotless. No spilled dirt, no dust, no dead plant material.
Keep the plants from touching each other. Put double-sided sticky tape around each planter.
P.S. The "moths" are probably whitefly's.
