My first fatality?

[catgrrrl]

Can anyone give me some advice?...

About 3 1/2 weeks ago, I got 4 phals of various types from Norman's. I had isolated them from my others orchids, and within 1 1/2 weeks of receiving them, one started exhibiting certain signs. A few of the flowers' edges turned brown and withered away. I thought it was just due to the age of the blooms (since it came that way from Norman's.) Then within a few more days, I noticed some of the leaves in the middle (not any of the outer top leaves) have developed mottled, grey/brown pits on the tops and bottoms and are turning yellow, and it's spreading to other areas of the plant. It looks very much like all of the pictures I've seen of the CymMv virus. I left it isolated because I haven't had the heart to dump it. I think I just have to do it. Right?

This is the same group I purchased from Norman's in which I got a Phal. Bellina that had signs of previous crown rot. Now one of the leaves of that plant developed a wierd yellowing tip that became more and more see-through and seemed to be spreading up the leaf. I decided to cut off the yellowing tip part with a sterilized shear and I dusted the leaf edge with cinnamon. I should have a taken a picture and posted it to see if anyone had any ideas, but I couldn't find my camera cable to download it - and it was just growing and constantly taunting me... I guess I should just keep and eye on it and hope that one doesn't have something nasty, too.

What would anyone of you do?

I'm not enjoying the ones I got from Norman's...
