Received a Japanese Vanda as a Gift… Help

[Accidentalnurse]

I’ve had this Vanda since March 18th - it was a gift from Japan from a very close friend and I really want it to grow. The friend knew I loved plants and has been asking every few days for updates… I’m currently pretty sad thinking this guy isn’t gonna make it. The roots were small but the plant looked good overall. I posted on Reddit in r/orchids and got one comment of advice.

We’re now at April 2nd, the top leaf is yellowing/browning and there’s been no new root growth.

He sits in a south facing window getting about 2000-4000 foot candles of light a day for about 10-12 hours, I’ve been doing the 15 minute soaks in rooting hormone water like someone recommended in a reddit post, and I’ve been rinsing the roots under water in the morning and evening. The roots look more brown/cracked, there’s no additional growth and the leaf is looking worse. The room is around 70° and the humidity stays at high 50s low 60s.

What can I do? I really want to save him.

Included updated photos from today. Should I plan a funeral? It’s crazy how invested I am in this.
