Out out brown spot!

[Velamen]

Hello Orchid Growers,

The attached pic is of one of my Cattleyas. Given my inexperience I have a question about the Cattleya shown in the first picture.

Previously, two leaves on this plant had turned yellow/brown and had to be removed. At that time, over a month ago, I was told to check the roots. Sure enough, there was a good amount of rotted roots. I very carefully removed all dead and decaying roots and repotted the plant. For 3 weeks I left the plant stay in partial shade, further away from the overhanging grow lights.

However, while the rest of the plant is doing well and, as you can see from the second picture, is sending up a blossom sheath, I wonder about the bruise/brown spot on the leaf in the first picture. I'm sure I cut out the dead roots. Maybe it's shock from the repotting?

Thanks so much up front for reading this and for providing any insight/solution you may have.

Happy orchid growing!

I closer picture of the leaf would be great. But as far as I can tell it may be cellular collapse. Did is get too close to a hot window or something? It get too cold?

Thanks, Katherine. I will post a closer pic tomorrow.

Best,

Hi Katherine et al.,

Here is a close-up of the brown spot on the leaf of my cattleya. I noticed that the other side of the leaf is unaffected. The second pic is of the back of the leaf. So far, the spot has not spread or gotten worse.

Thanks to all for your help!

Best,

Don

i don't know. Could it have gotten too close to a light?
Maybe someone else will weigh in. I would just keep an eye on it.

Thanks. I didn't place it too close to a light. For now, though, it's not getting worse. Will keep an eye.
