Need help w/ phalaenopsis! mold? scales? bad roots?

[Jenn4a]

All this new stuff is kind of overwhelming

There is a smell of mold, moss, and algae.
My plan is to let the pot air out since it is still pretty moist inside. I really don't want to repot just yet as the Phal is still blooming and most of the roots look healthy. Unless I am told I really need to ASAP.
Nearly all of the roots inside the medium are green; there's a few that look like that have algae, white stuff, or some black on it.

I do think some of the white stuff on the bark is salt residue, but I included a pic of the gray/white spider web looking fuzz, and the white fuzzy thing.
There's also a photo of the stem/crown area with white particles stuck in it.

Other than the spots, the possible mold, dried top roots, and possible parasites, I think the orchid is healthy.
I included pics of the whole orchid and some new growth?

Also, are these brown ovalish areas something to be concerned about?
Included a picture of front and back.


Fuzz and web


Same leaf with two dark soft spots.


are the dark spots on the bottom side problematic?
