let me tell you I had to battle with mites for the entire flowering phase... and it's hard hard work to get the harvest off decent. Mold on top of that.. the spider mites will just want to stay inside (and come in from the outside) because of the winter cold/wet weather. Mold is usually caused by high humidity. Though mites and mold live for the opposite in moisture levels, it may be wise to dip your entire plant in neem oil (if it's vegetative). Is the mold powdery mildew or bud mold? if it's the latter then you are probably out of luck at this point.
