Very Sick Vanda: Sarao Cherry Bomb

[Synrosion]

I got this orchid a couple of months back. It was doing fine, but it went downhill fast. The roots almost all died, and it lost almost all its leaves. I was told it had some sickness, and I just soaked it every day since that's all I was able to do. It got better Recently with a couple of healthy roots and a tiny new knob for a new spike grew, and a new leaf started. But the knob fell off a couple of days ago, and it just lost one of its healthy roots. I very much want this orchid to survive, so I need advice. I live in Florida and fertilize all my orchids every week, starting last week. I soak them every other day. Advice would be appreciated greatly.
