Vanda leaves black and yellow!!

[beachgirl]

Hi all
I bought this vanda for my mom a few years ago. It has flowered often, a beautiful purple. After the last flowers died the plant fell to the ground and then I began to see black spots on the leaves and now the lower leaves are yellow and dying. After I saw the spots I sprayed it down with hydrogen peroxide which did not seem to do any good. It has a baby growing off the lower side which you can see in one of the photos so I don't think its dying. Roots I think are relatively ok. Can anyone help me figure out what this is and what to do? I live in south florida and we had a rainy year last year.
Thanks!

You already found Marla's similar thread. I would contact local growers for advice.
