| I think the correct spelling is Cattleya velutina. It's definitely not normal for a Cattleya, especially a seedling to loose leaves in this manner. As far as I know this Cattleya likes typical Cattleya conditions. I did come across a couple of places that indicated it was an intermediate to warm grower rather then just an intermediate grower which suggests to me it might not be as tolerant of cool temps as other Catts. That added to the fact that it appears to still be a seedling makes me think of temps as a first possibility, especially cool in combination with humid or moist. What conditions are you growing it in? Has it been growing?
