well, get a dehumidifier. if you cant control the humidity during flower your asking for budrot/powederymildew/mold. the fact its only in a few spots dont matter, in 2-3 weeks your whole plant will be covered with it. how do you plan on drying the bud too? humidity like that during drying is as i said before a sure way to get moldy buds/bud rot. you dont really have a choice, you need to get the humidity under control asap.
