This is my first and largest Cym. (noid). I just repotted it 2 weeks ago...it was in the growers pot and the medium was really broken down. Had quite a few dead roots (which I trimmed) then put it in fresh medium. When I trimmed, I used a sterilized (boiling water) pair of scissors. Prior to the repot, a couple of the leaves started doing what's in the picture. At first it was just a small area on 2 of what appears to be the oldest leaves and I didn't think anything of it because I attributed it to the old medium. I got it a few months ago and put off doing the repot -- I know, I know...but it happened.

Also, I'm noticing a lot of browned tips...you can see the one that's taken over on the visible leaf. I've read this is attributed to too much fert but that can't be the case here as I'm horrible about remembering to fert my orchids and when I do remember (about every 2-3 weeks) I used a weak solution.

I thought once I repotted it, it would begin to bounce back. But...it's gradually gotten worse and it's taking over more of the leaves.

Is this disease or just a natural process? Hopefully you can tell by the pictures.

I do know that it's been unseasonably cold and wet the past 2-3 weeks here but I also read the Cym. are OK w/cooler temps.

I should also add that it's only affecting the leaves of what appears to be the 2 oldest pbulbs (correct term for Cym?)...the 2 newer pbulbs and the 2 newest growths appears to be blemish free.

What do you think?

Thanks!
