Interesting, but I'm still not certain why you would have the problem while
others don't.

I have been happier (i.e., the plants have been...) since switching to the
MSU fertilizer for RO. Maybe that formula addresses the issues you had
better than I realized.

Thanks for the input.

If I read that correctly, Pat, I would guess that the RO water played no
role in your experience, but that you "over-alkalinized" things, probably
because - as others have helped me see - leachate pH control is not
overly reliable with orchids.


Hey Ray,

You would be guessing wrong, but thanks. Thanks to help from Va Tech hort
department, extensions services of the states of MD, VA, NC, and CA, Karen
at Peters Lab, and the tech department of Scotts I know exactly what
happened. Dr. Joyce Latimer at Tech personally handled my case and was
the one dealing with the other state's extension services. Looking for
help, Joyce presented my case at a national extension meeting. The state
did this to me, they were most helpful in resolving it.
