Need help with one of my Masdevallia's

[King_of_orchid_growing:)]

Temperature tolerance really depends on the type of Masdevallia in question.

Any species that are usually found above 2,600 meters is very difficult for people with warm summers to grow.

Any hybrid with species found above 2,600 m in its heritage are the ones to watch out for.

That's good to know. I will have to check, although I know for a fact that I was only able to determine the heritage of one of them as it was listed beside the name. The other one I have no idea although I did research the KEW files and other places. I will have to see which one it is again.

For the moment at least, the leaf phenomenon seems to have stopped and I have slightly reduced my watering a bit just to be on the safe side. I have also put it in small net pot to see how it will react.

And they are kind of hiding behind one of my rather large phal's (7 leaves, each leaf about a foot long), so they are getting plently of shaded light. I have not pulled out my light meter yet to take a reading but I did do that when I first got them in the winter and they were fine. Of course, the sun has shifted in the sky and the intensity of the sun has increased since then, so...

Thanks everyone for your input. I will just relax and let whatever happens happen from this point I guess.

I have had several masdies for about 6 months now and just recently repotted them into clay with sphag. All of the root systems looked great and i tend to keep them dripping wet most of the time. I have lower humidity and I personally think this helps counteract that problem. I also had them sitting where they got some direct afternoon sun and have had lots of new growth and lots of flowers and no sunburn. I say try it, they might like it. I did move them out of the hottest area when we had temps in the 90's. My growing area was still in the mid to high 80's though.

I have them right by one of the house's air vents, so they are getting some indirect air movement (they are on a countertop by the windowsill and the air vent is on the floor.

I too have low humidity in the house and had used some sphag and perlite mix to plant it as they were not doing well in the mix I originally was using. They seem to be doing much better since there are new growths. I don't let the sphag get completely dry, but I do monitor everyday the top layers and figure if the top is getting fairly dry it may be time to water again. Of course, that does not mean the inside is dry at all, but I did not push the sphag down at all so it is extremely loose and airy in there.
