Thez_yo ; Unfortunately your
Phalaenopsis stuartiana looks very desiccated.
This plant comes from the tropical jungles of the Philippines, 300 ft elevation.
This species needs much shadier conditions and good humidity.
It looks to be getting too much light. Also, this orchid likes to be kept much more moist,
as it doesn't have a dry rest period. It simply likes to "dry" out between waterings.
Orchids don't like being saturated.
However, the bark you have it in basically needs to be watered every/every other day,
as it must dry out too fast.
Remember, a dry phalaenopsis is a dead phalaenopsis
Good luck nursing your plants back to health
