welcome to the wonderfull fight with spidermites your yield will be down but spray now with food friendly sprays. use a good bomb like dr.doom then spray with 2nd type again repeat every 5 days i also use liquid ladybug all natural spray. after harvest. bomb and clean like hell.there tough little buggers and hid under leaves, walls,trays etc.good luck talk to grow store for more stuff. mites suck the juice from leaves.slowing growth and changing coloring of growth. pale or yellow if real bad.
