Agrees with soil not draining freely enough and seems to be compacting the roots.( based on the section pic)

Should show new growth signs soon suggesting It might be better to re-pot now in a looser airy soil that is bark based amended with rinsed grit and perlite for some substance to help retain moisture and still allow free draining

Thanks for the reply, that definitely seems to be the best answer. Though some of these end segments are wilting away, the plant is still vigorously growing. Especially since I've had to pinch off about 2-3 segments per branch since this began wilting.

As seen below, it seems to still keep up with what dies by growing so much back. I just wasn't sure what the problem could be, and therefore didn't know how to keep it from continuing despite the new growth.

I'd still add more perlite to that mix, looks a bit too rich to me.

I agree. Lighten that mix up considerably, and then you'll be able to water copiously a time or two a week during the main growth season. I strongly recommend a mix that is mostly fine-grade "Orchid Bark," with Perlite added...and just a pinch of potting mix/African violet soil to increase moisture retention.
