yellowing leaves-Masdevallia Floribunda

[VickiC]

Thank you, Terri and Yvan.

None of my other orchid-family members have complained about the water change, but I guess what people say is right: there's one in every bunch. lol

So, I'll buy a gallon of distilled water, just for Ms. Masdi. A gallon should last her quite a while.

After I posted my question to you, I took another look in my Exo Terra, and I noticed then that my Maxillaria variabilis 'Grace' has just a very tiny tinge on one of it's leaves, so I think I'm gonna share the gallon of distilled with her, too.

Let me know, please, if you advise differently.
Thanks again for your help,
Vicki
