I have an orchid that has spots on two leaves, and no spot on the other leaves. Among these two leaves with spots, one (named "Leaf A") has more visible/pronounced/impressive spots than the other leaf (named "Leaf B").
Look at my orchid (the one within the black borders):
The arrow indicates Leaf A.
You can better see this leaf here:
Behind this Leaf A, you can see another leaf with no spots. Behind the latter, you can see another leaf with light green : it's Leaf B (its spots are a bit visible).
Is it normal for an orchid to have spots in a leaf? Is it normal for an orchid to have one or two leaves with spots?
