Vanda dropping leaves, can this be saved?

[captainbug]

I mean, watching the few YouTube videos that really exist on the topic of Fusairum, it does "exhibit signs". The way the leaves yellow from the base and drop. The way the roots are choked and develop a bit of callous around the choke points.

But honestly, all of this coincides with having really unfortunate crappy care thanks to this being my very first Vanda. I don't think I'm willing to go chopping off any more roots, and certainly not stem, just to try and find out. I'm also not just going to "throw it away" until it's dead beyond dead.

So far I've removed it from any pot and media. It's hung on a wire once again and placed in my windowsill. The house is at 73F pretty consistently and it gets sun through the window well enough. I'm considering purchasing additional grow lights.

I'm fixing to order some fertilizer to start soaking it in weekly.

Water-wise, I've been showering with it daily for the last 6 or 7 days. Nice steamy warm shower, directly in the spray for about 10 minutes, then again before I get out for another 5 or so. Right now it's having a soak in the sink after it just had a shower. The roots aren't getting terribly plump, and only a few have any green to them. See the closeup pictures attached for a better description than I can give. One included of it still in the water after a good 45 minutes.

It's lost a couple more leaves, and I know it's going to lose at least one more. However, the next leaf up isn't showing any sign of death at the base.
