Put a teaspoon of hydrogen peroxide in the crown on the dark part. If
it fizzes, the plant has crown rot or some such, and the hydrogen
peroxide is sterilizing it. After a few minutes, tip out the rest of
the hydrogen peroxide, if there's any left standing in the crown.
Repeat this every three days for a total of about 5 treatments. I've
managed to arrest crown rot this way.
Also, take the plant out of the pot and see what the roots are doing.
If they're rotting, cut out the rotten parts and spray the rest of the
roots with Physan 20 (1 T per gallon of water). Then repot in fresh
media. That's what I would do, but you'll probably get better advice
from more experienced growers.
Good luck.

I just checked the growth point with a magnifing glass and found the

of a new leaf (about 1/4" long). I also found a small dark area
- crown
rot???? I attached a picture of the growth point.
Would it be prudent to assume that this dark area is the start of crown
rot
and if so what should I do. BTW I normally water the plant on
Saturday
morning but did not yesterday thinking that I should let it
dry out a bit.
Good idea or not?
One last point the plant was purchased last December from a local
grower that
I have pruchased plants from for several years. I would go
show it to them
but they closed down there business and there are not
more local growers in
my area.
Thanks...

If everything you have stated is correct it could be that a
relatively new
leaf has started growing or a new one is in the process of coming
through.
The new leaves use the old leaves resources when they grow.
You didn't mention anything about new growths.......are there any?

I have a phal that up until last week looked as healthy as can be.
New
spike, old spike with new side shoot, leaves green and trugid -
very
nice. This past Wednesday the lowest leaf started to turn yellow
all
over and today it is bright yellow - still turgid but very yellow.
Climate where the orchid is growing has not changed since I got it
several months ago. It is watered every Saturday morning. No bugs
that
I can see. No crown rot that I can detect. It never has wet feet.
Any ideas what is going on with this orchid and what if anything
should
be done with it?
Thanks...
