Vanda- yellow leaves- old roots fell off.

[Orchid Davantage]

I will do my best. While it is on the mend, should I soak it twice a week for a shorter time? I mist my two other ones every day and dip them once a week. What should I do about this one? The new root is coming on the side, it makes it difficult to soak for an extended amount of time. It is in a bucket of water now, after that it is going to join all the other orchids in a sun room. It has lights and humidifiers.
