cattleya leaf color
I seem to read conflicting advice on the ideal color for cattleya leaves. I know it's dependent on the amount of light. Most of my catts have a medium green shade but one large one in particular has quite a bit of purple on the back side of its leaves. It's on a glass-top table quite close to the wall of windows, which is a southeast exposure. The rest of the catts are on my shelf unit under fluorescent light. And another question: some of these are developing yellow blotches on the leaves. Other than that, they seem healthy and periodically produce blooms. (The big one, however, has not bloomed yet. Maybe because it's been repotted a couple times.) Am I doing something wrong?
