Well two of the leaves were slightly damaged (cut) on the edges of the leaves when I bought them, and I heard somewhere that leaves could split as a sign of dehydration which they were a little bit when I got them but nothing dramatic, overall healthy. But otherwise no cats or other animals that could harm them. The only thing that I'm noticing is that more and more orchids get dried up "middle line" so it concerns me a little bit that more leaves would split in half lengthwise. Could it be that I'm under watering them slightly. I usually water them once around 80% of the roots get that silver tint.
Thanks in advance
