Condensation on my Cattleya's newest pseudobulb

[cabbit]

This feels like a silly question, but I'm already here typing so I suppose I'll ask it. I keep on seeing drops of water, kind of like dew, on the new growth of my cattleya. It's not because of watering, I know that much, because whether I've watered recently or not it just keeps on happening. And it really is only the new pseudobulb that's affected, I've checked.

I'm not really too concerned about it, but I am curious. Is it because of the humidity in the air (and why, then, is only one part of the plant affected?). Is it just something that happens occasionally? Or could it be some sort of rot that's created more moisture on that part of the stem? (if that is the case, I AM concerned)

I'd love to know what's causing this if anyone has any ideas
