Black spots yellowing on my Vanda

[orchidee_de_la_mer]

Hi!

Errrrrr... I keep on having issues with the same plant!

I left my Vanda inside, in a West facing window... it's leaves are starting to look shrively. It had, on 3 of it's leaves, a set of big black spots, growing and growing on those same 3. So I chopped a part of these leaves off! And then, just lightly sprinkled the tchopped-off tips with cinamon. Now, two weeks later, these leaves are turning yellow and the scar is making another big, gigantic black spot.

I tried to research it, but I don't know weather it could be fungus, massive lack of humidity, to much sulight or something else...

Oh! And i just bought some kind of humidifier yesterday as well... not sure if it helps...

Please help!!!! I love this plant!!!!

Thank's!

P.S.
I included a picture of my set up just incase...

It looks like leaf tip burn. If it is a black circle, it's a fungus ring.

Use RO/DI water if you're not already. Or cut back on the fertilizer. Make sure your fertilizer is urea free.
