I was wondering about that, what had I done wrong.

The plant is in a cold north facing bedroom, only heated if we
have family to stay. It is on a table near a window but not
close enough to touch it. We have had a water problem in a
corner of that room, in January with all the rain, but not near
the plant. Given the speed with which it has taken hold, I
don't think it originated in January. I water from the bottom
first thing in the morning, so I don't think it is me!

I have severed the offend leaves close to the plant, where they
look quite healthy, so just keeping my fingers crossed.




I water my orchids, except for the large standard Cymbidiums, by placing the
pots in a bucket of pot deep water, with fertiliser 3 out of 4 waterings,
and leaving them there for at least half an hour to soak. I then drain them
off thoroughly and place them back on their windowsills. I do this about
once a week, slightly more often in summer, slightly less in winter.
The growers use a flooding/draining system to their benches when they grow
orchids so my system is similar.
