Cattleya leaf turning black/brown - normal, or should I freak out?
I bought this orchid in December at Lowe's. I haven't repotted it at all, so I'm not sure what the media is, besides that there is gravel at the top. I've been watering approximately once a week.
Recently, I noticed the end of this leaf turning yellow, and then black/brown. Is this the normal way leaves die off from the pseudobulb, or is it a sign of a problem? Also, do the pseudobulbs seem excessively shriveled? I've been wondering if I should water more, or repot to see if the roots are OK. The plant does have two new growths forming, one of which you can see in the picture in front of the damaged leaf.
Thank you for your help!
