Discoloration on phalaenopsis leaves

[EricArthur]

Hello! I’m pretty new to orchids and have only one that for the most part has seemed pretty happy. However, I just noticed that there is some black splotchy discoloration on the edges of the leaves. There’s also a darker spot by the roots that is concerning me. Is this something to worry about? I water it once a week but could reduce that if it’s being overwatered. I was also thinking of applying some cinnamon to the black spot if this happens to be a fungal infection. I’d appreciate any help!

Thank you,

Eric
