Jared, I think you need to relax. If you just added the humidifer a week ago, there hasn't been enough time for your plants to react. If things aren't getting worse, then they are getting better. Growing pitchers will let you know all is well. But it may take a couple months.
I never fertilize my carnivorous plants either. When you have a plant willing to feed itself, let it. You can overfeed carnivorous plants by feeding them extra insects. And its easy to over do the added fertilizer too.
Growers of carnivorous plants work hard to find potting medium with no nutritional value: Milled peat that hasn't been fortified, natural long fibered sphagnum moss, perlite ... I have been thinking about experimenting with some of the planting mediums used in hydroponics.
Tarev, I'm surprised your plant is surviving its soaking but also not surprised. My daughter has her orchids sitting in saucers of water. It works for her; the rest of us would have rooten orchids.
My husband and I lived in Oakdale for 30 years before moving to Reno. Be brave and find something that holds water (I love those little stock tubs from the feed store. They are cheap and won't break up in the sun). Dig a hole and stick it in the ground, fill it with peat and perlite and plant those Sarracenias. You will be amazed at how they do. The tubs should only be about a foot deep.
I have mine planted in bogs in Reno (Zone 7a). I have to cover them in the winter but they do great - unless the raccoons dig them up.
