Hi all.
I recently purchased this Cattleya percivaliana coerulea. It looked like it was growing fine. Some yellowing and browning on the leaves, but I thought it wasn't a problem.
After being away for the weekend, I came back to find a weird discoloration on the newest leaf. It's vaguely ring-shaped and lighter in color than the surrounding tissue.
It's not visible from the back of the leaf, image below, along with images of yellowing and browning on other leaves.
Can someone ID these issues? If it is a virus, I'd like to reach out to the seller. Thank you.
