Some good advice above, but I'd like to take a moment to dispel a couple of apparent misconceptions.

Misting: You stated you mist the plants daily. If that is the roots, fine. If you are misting the plant, in hope of improving the humidity, don't. Firstly, to raise the humidity, you need to mist the air, and have it evaporate. Wetting the plant doesn't do that, and can set you up for infections.

Humidity near the pool: As water evaporates, it is quickly dispersed uniformly into the atmosphere. The RH might be higher about a foot from the water, but much farther than that, it will be no different than whatever is ambient, and having lived in GA for seven years, I guarantee its plenty!

Light: Those are considered to be "strap-leaved" vandaceous plants, so will not handle direct Georgia sunlight. If they've been indoors, you will need to transition the plant slowly into brighter conditions, ending up with dappled shade, not full sun, over a period of a week or two. I'd bet that about 50% is the maximum they should get.
