Sounds like you overwatered a bit, or salts built up in the soil. Repot your plant into a fast draining soil. Check for root rot anyway. If you don't like the look of aerial roots, you can cut them off, but also you can try to cut off the ends of the vines and root them.

I wonder if you might have a Philodendron, Pothos are much less likely to make aerial roots like you describe.

It would help if you could post some photos to give us a clearer view of what's happening.

thanks so much for the help. i have yet to re-pot this little guy, but i will after you all take a look at the photos and still think it's the best option. attached you can see the yellow/brown color change near the pot, the longest of the growing air roots, and also more color/size/root changes near the end of one vine. thanks again.

It is indeed a Pothos with long aerial roots. Not a problem at all, actually very cool. When you repot, you could provide something for your vine to climb up, as it seems ready to do. As a vine, that's what it would do naturally, climb up a tree trunk.

It looks like a possibly toxic level of salt/lime build up has happened in the pot, a condition that warrants repotting. Even if you have no option but tap water, using a pot with a hole, then watering thoroughly so excess water runs out of the hole (and completely away, not trapped in a drip saucer,) can prevent that in the future. If you have the option to catch some rain water, your plant would appreciate that very much when possible. Distilled water, and condensate from a dehumidifier or A/C are also sources of water with no added chemicals.

Sorry for the delayed reply, for some reason I didn't see the discussion pop back up on the forum page, and haven't checked email for a few days. You may find some inspiration in regard to goals for your plant in this extensive discussion about epiphytic vines. (Tons of pics too.)
