I'll add one more thing that I think no one's addressed yet...

The roots on the Vanda that's doing well, are very thin. I make this a point because, eventually, if the plant doesn't start developing strong, thick roots, the same fate will befall it that which happened to the Vanda that isn't doing so well.

There is a cause for spindly roots on Vandas, but right now I can't pinpoint it. I think it's from not enough water.
