Like to spritz them lightly with a spray bottle or to have them under a mister continuously?
A light spritzing will dry out quickly so shouldn't cause problems, though I wouldn't do it on buds for fear of supporting mold growth. (Although if it really is humid then they're not going to dry as fast...)
Continuous misting could cause mildew/mold problems, I would fear.
Cannabis likes bright sun. If I were you, I'd just make sure your plants are carefully watered and maybe look at doing a little cautious defoliation to open them up for better air circulation if they're too bushy (but even that I'd be really cautious about).
Just my .02...
