After reading all these posts, I’m leaning toward temperatures as being the culprit. People in my house are ridiculous regarding this place remaining a refrigerator. I’m going to keep everything the same, but add a heat mat. Y’all are great. Thank you. in addition, you were right on about the intensity of the light. Moving things back from my window a bit, improved the health of most my orchids.
