Phaleonopsis health?
 

Hello :)
So i bought a phal that was on a sale, so maybe it was a bit neglected. Anyways, there's a few problems(?). The roots turn grey too quickly after watering. Some of the roots look yellow/rotting. The leaves are patchy and some of the edges are dark reddish. The bottom of the stem is also kinda dark red. Air roots are dried up, should i cut them? Also, should i take everything out and cut the yellow roots? If i do that, can i pot in the same medium?
ps. They're near a west window but not directly on sun

(I was going to upload pictures but i can't)

OK, go make 5 posts somewhere, say 'Great' or something to random posts and then it will allow yu to post pics. Pics are a great help.

What's it potted in?

Deffo no direct sun, or they will burn badly.

Personally I never cut roots.

The danger here is that this is a 'Buy-to-Die' orchid that has been potted in moss and grown on without repotting so that when it is sold, it is on the point of going downhill rapidly.
The moss by then is so dense and broken down that when it is wet, no air can get thru to the roots, it gets overwatered and the roots all start to die.

Hello!
I am very new to orchids too but from my previous research, I think I can answer some of your questions.
By the way though, what is your medium? My guess is decaying sphagnum moss.

I suspect your phal is suffering from root rot.

It is normal for aerial roots, and roots near the top to be silver. DO NOT OVERWATER.

I was told that unless the phal is blooming, it should be repotted as soon as it gets home. I have lost all roots on one of my phals due to root loss, my second phal was a sick one bought at a sale as well. I acted quickly and think I have contained the root rot this time. I have a thread "Rescue Experiment: Root Rot" underneath. You should check it out if you are going to repot.

When you say leaves are "patchy" does this mean its yellowing? I suspect that due to root ross from rot, it is unable to sustain all the leaves therefore you may lose a few of the lower leaves (unless its the last 2 or 3 which seem to be last a bit more).

When you say your aerial roots are "all dried up", is it just the color or is it all shriveled up and doesn't feel firm? My guess is that it looks shriveled up and doesn't have that firmness to it? It was damaged possibly and therefore died. You can take a sterile blade and cut all the dead and slightly into the healthy root. Also note, color does not determine the health of the root. I have few completely white roots which are healthy. They are simply not photosynthesizing. However, they can still absorb water and nutrients for a plant.

For the stem/spike, I am guessing you have no flowers? The dark red sounds like the stem/spike is ready to start drying. Cut it back slightly above the first spike.

Well, i don't think it's /that/ bad, maybe i described it too harshly, i'll post pictures as soon as possible.
The medium is bark. It does have flowers. It's just the part of the roots and their color i'm concerned about. And the aerial roots are dry, shriveled.
As for the leaves, it's green and silver patches. I thought it was some kind of dirt but i can't wash it.
