BigBill said:I am alarmed to see this "damage" and I do not like it!
At first I was thinking insect damage on the underside of the leaf eventually making itself visible on the upper surface of the leaf.
BUT in your last image of the underside of a leaf, between the 2 spikes or inflorescences, those irregular yellowish markings look like it could be a virus! And if it is, that is bad because there is no cure for it.

We have no information as to the light, the temperature and watering details but I am concerned all the same.

Thank you for your input BigBill I am very concerned about it because it's the first time I see something that seems abnormal to me in my orchid leaves. I have had it for almost an year and never had a problem until now.

I have inspected the orchid thoughrouly and haven't seen any kind of bugs on it. I am very afraid it could be a fungus or like you said a virus. I am not sure how to tell the difference though.

I inspected all my other orchids too now and there's another Phal with the same type of spots in one of its leaves but just four little circles. That is what is making me wonder if this could be a serious problem.

To give you a little more details, the temperatures I keep my orchids right now range from 65 to 70 degrees. Humidity usually between 45-55. They get a lot of bright light but they are not in a windowsill and don t get any sun directly on them. At this time of the year, I usually water once a week or twice if the pot feels very light.
