Yes, it looks like your phal is stressed. I suspect root issues. Please unpot and take a look at the roots. Check out both of the following links. The first is the RVO care page link to repotting a phalaenopsis orchid (it also has the same video as the second link below.)

Since phals do not have p-bulbs, they need to remain moist around their roots (Moist - not wet). In this way they are similar to paph (slipper orchids).
Best of luck and welcome to our community.
