Phalaenopsis brown roots & reddish leaf

[MiffyThePhalaenopsis]

Hi, first time having an orchid so I don't know much other than what I've looked online. I got her as a present so I didn't really learn much before getting her.

So, I pulled Miffy(my orchid) out from her plant medium to check on any root rot, and they're still very much green. Her leaves look very much healthy and green, but the leaves on the same side of the plant turn yellow and fall off. I saw online that it's normal for the plant's cycle, but this time the leaf has a reddish hue to it. She also has a small brown area on the edge of her leaf so I don't know if it means anything.

I also don't know if the roots are fine. The bottoms look healthy but the top area looks brown and woody. She's been growing a new leaf so I'm getting conflicting information on if she's healthy or not. I also saw online that cinnamon is good for preventing fungal infections, is that true?

Also, because I see dust on the leaves, would it be a good idea to wipe them down with a moist paper towel to get the dust off? I haven't done that yet in case it might hurt her but I figure I might ask. Sorry for the wall of text, I'm still fairly new to caring for plants.

I was soaking her for an hour when I took the photo. I only water her once a week.
