HELP!!! Phalaenopsis leaves look ill.

[cmcmonigle]

I am very careful not get water on the leaves or base of the plant while I water it. The roots sit in the middle of the pot and are about 3-4 inches from the bottom of the pot. I have had the plant in that pot for the past five months I've had it since it was a gift and the container it was in was garbage. Could changing the mulch and cutting the spike in the same day stress the plant to do this? Also, should I treat the cut part of the leaf after I cut it? I used cinnamon on the cut spike since I read it was an effective fungicide. Thank you so much for your input. This plant has special meaning to me and I would love to keep it for many years to come.
