Phal leaf yellowing do I need to worry?

[Phalaenoptics]

@shadeflower thank you for your insight! I do always try to look at the overall health of the plant and troubleshoot any potential problems. I enjoy looking over all my plants daily just to make sure everything is doing well. It gives me a lot of pleasure to see them thriving. Getting over that "new parent" phase where everything is a cause for concern.

@ES this makes perfect sense to me! Learning this concept about phals and water intake/water needs really helped me learn to manage my care.
