Sorry but I don't know where folks get these ideas as

"i know repotting it again could kill it since it was probably already stressed from the first repot. what should i do?"

If unpotted already it needs to be repotted. Not sure what your 2nd pic shows, is that from BEFORE you unpotted?

While I don't grow this plant I do grow other Aroids & just repot them when they need it.

I'd crumble off any mushy roots, or any that are brittle & dead. Then sprinkle w/ cinnamon (anti-fungal), pot in some fresh mix, water in well & then give it time to recover.

thanks, i appreciate your response.

the second pic is after i repotted, before i pulled the plant out of the pot.

i guess i read that the plant would be "Stressed" if i repotted it. what type of soil do you use for your aroids?

Use a nice porous mix..........you can use regular potting soil mixed with equal amounts of perlite and orchid soil (or just a fine bark mulch). Maybe throw in a handful of compost. mix well. This will moisten but hold a lot of air space. In the wild these guys climb trees and send their roots into all the decayed bark and moss etc. that collects in pockets along the branches etc. If the plant wilts (if it lost more roots than will support it) you can temporarily raise the humidity around it (put it in a large clear plastic bag with the top slightly open)

was the new potting mix holding too much water or had too much fertilizer? The yellowing could be due to too little or too much water, or fertilizer or sudden change in temperature. Did it get you change its location? Was it getting direct sunlight or a cold draft? If you haven't already repotted, put the roots in water for sometime while you decide what to do next. If it is due to fertilizer, this could help wash it out.

A couple of leaves yellowing after repotting should not be a cause alarm unless the trend continues.
