I had previously posted a thread on the plant and had the name wrong and pictures that did not show fully what is happening with this plant. This morning when I went to the orchid room to check my plants this plant now has 2 yellow leaves and black spots on one of them. This plant was in spike when it was purchased last November so it has not been under proper light until it finished blooming last week. My question is: Is the yellowing of leaves a normal aging process of the oldest leaf. What do the black spots mean.(is the plant not getting enough water. Photos are posted under member photos gallery under my user name of Dennisl142. Thanks
