Hi! Had this for few months. There are few-several leaves that turns yellow which I know is normal. But this lit baby leaf, blackness started from bottom to up. I wonder what is wrong with it.

. Yes, fairly new to brassosvola, and it's so lovely orchid which I got for my husband past July...
Any help, advices and tips which I would greatly appreciate. And also how to grow them.

You can see the lit baby leaf which it has black on it. What is causing it? Hmmm...

That's what it looks like right now...

Other pic again, as you can see the black on it one leaf.
Looking forward to hear from you! Merry Christmas and Happy New Year!
Psst! If you click on 1st and 3rd pic and enlarge the pic, it's on slightly left, near the pot. (Not in middle of plant, hee! Goof luck!) I hope you guys can see it.
