Feeding Vanda Orachoon x Vanda tessellata

[greenhouseFrog]

I was gifted this plant by a member of my local orchid society—thanks Jim! Luckily, I have the space to accept things like this, but my experience with vandaceous types has been limited to small seedlings.

Since I’ve had it I’ve been spraying the roots till the point of runoff twice a day with the same 25PPM nitrate solution my mounted plants get, but I feel like that’s not what it wants—it seems like everyone is feeding their Vandas quite heavily.

I mix up a 100PPM nitrate solution from concentrated stock everyday for my solitary mounted Catasetum; would this Vanda appreciate the same amount of feed as the Catasetum and does being in bloom change how I’d feed it?

Thanks in advance for any and all input/criticism!
