Need help with stressed/recovering Phal (lacking roots, yellowing leaves)

[onyxorchids]

Hello! I have a phal I'm determined to save, and as I'm still extremely new to this hobby I would love a second opinion on what to do.

I recently received my first orchid from a family friend who was also new to orchids. And while it certainly doesn't make me appreciate the gift any less, I've since dealt with a lot of issues that had previously gone unnoticed (mealybug infestation, severe root rot, etc.). This phal has been through a lot lately. : (

We are now mealybug-free, repotted into fresh & non-broken-down media (medium orchid bark), the spike has been cut to conserve energy, and all rotten roots have been removed. Unfortunately, that left it with only one actually decent-looking root.

My routine has been to mist its good root and the non-dying leaves as often during daytime as possible, without leaving anything damp 24/7, and without letting any water collect in the crown area. I let it dry from evening on/overnight. I've been using an orchid spray-fertilizer as per its instructions (weakly, weekly).

I've included pictures - the phal now appears to be losing at least 2 of its bottom leaves, likely because it simply can't sustain them anymore. This is shown in the most recent photo.

So, my question is whether anyone has any additional advice on how to save a stressed orchid lacking roots? I've read advice ranging from treating it about the same as any other resting orchid, to the sphag 'n bag method (which I may try once removing the dead leaves is easier; don't want moisture encouraging rot) - but without much experience it's difficult to know which to follow. Anything at all would be much appreciated!!

I also have one quick question regarding my other phal (a mini), simply what to do about two odd-looking roots - one appears almost fluffy like sphagnum moss, and the other is thin, brown, and woody, but with seemingly healthy tissue on either side. I don't want to cut anything unless it's necessary - last 2 pictures are of the mini's roots.

Again, sorry if this ended up a little lengthy, but I'd very much appreciate anything any of you have to add!! : )
