Root rot, moth orchid? How to fix this?

[WhiteRabbit]

Another helpful tool is a bamboo kabob skewer. Gently twist one into the media, about midway between center and edge if pot (or closer ro center). To check moistness of media, remove the skewer, touch it (the part that has been in the media) to your cheek or upper lip. If there is moisture, skewer will feel damp, or even just cool to your skin. Replace skewer in same spot as it was.

For Phals, skewer should feel just cool (not damp), or dry before watering again.

Some styro in the center of the pot, in plant's root mass, is helpful as well. Helps avoid the wet center, while rest of media is dry, as well as makes a nice air pocket.
