Have you tried disinfecting the room, benches, etc.?

So, I am doing this in my home, and I use a repotting mat, that gets cleaned and disinfected along with tools, in an office for anything that might get messy. Otherwise, they just sit on shelves. I've never had any of these things before to my knowledge either.

Rhizoctonia tends to be a disease of plants with roots suffocating in old, decaying media. How long since they were repotted?

The phals and zygo had just been repotted within the month. I've never seen anything like it. The roots almost looked like they were liquefying through the clear pots. It was crazy. The leaves looked identical to an AOS webinar on disease, though.

How close to the lights are your Phals? They prefer lower light than the other orchids you mentioned. High light will cause leaf yellowing.
|
Yes, but these were yellowing and falling off within a couple days. My phals have the weakest lights at about 12-24 inches. The DLI is about 8-12 across the map.

Did you repot the Cycnoches while in leaf? It's better to repot them only when dormant, or many roots are damaged.
|
I've never repotted it. I just got it this year, and it's been in leaf the whole time. No problems until now. It just started getting new root growth within the past week. I don't know what's going on. I'm going crazy. Thank you!
