Good luck Alice! I know a lot of experts said that super thrive doesn't work but I swear it does for me. I was able to bring to life my dying Vanda (due to black rot), taking the risks of cutting off the stem with no signs of any root to now having multiple roots. This little Vanda is not ready for prime time yet but I'm hoping it will re bloom this year.
I think soaking them with the blooming food probably helps feed the Vanda's better too. I just make sure that following day it gets really dried well to avoid fungus growth.
