pins like evaporation.

I would put a light covering layer of verm on top and leave the lid cracked open or some vent holes opened up.  Check your mister, it should be a fine mist. You want a fine mist that barely covers your tub, 2-3 times a day.

I do one good spritz toward each wall--from 2 feet way away--on a downward angle--2-3 times a day.  If your tub is too dry, pins will often form near the walls, if the walls are also misted--making for an easy indicator of a dry tub.   

You can stop using the fan, chances are it isn't creating FAE.

So, wetting the walls 2 to 3 times per day will create the proper surface humidity for evaporation to take place and pinning to occur? Fans are great to help with this if you're set up for it but what you are describing sounds like drowning your sub and making puddles along the walls beneath your sub. Your hygrometer is a liar and you need surface humidity not tub humidity. While you can't have the first without the second you can definitely have the second without the first.
