I actually got a couple weeks ago. It is just a simple Phal hybrid that I picked up off a sales rack. I have it by a window and my grow rack for my CPs so it gets plenty of filtered light and about 14 hours of light. I'm not sure what the humidity is in my room, but I think in November it was around 45%.
When I got home from work today I went to check on my plants and I noticed one of the Phal leaves was drooping seriously. I went to touch it and the outside half of the leave was very soggy and mushy (except around the tip). All the other leaves (4 large and a small or two) all appeared fine.
What could be the cause of this? Is it a disease or did I overwater it? I watered it about six days ago and that is the only time I have watered it since I got it. The potting mix was dry when I got it, but not bone dry.
Thanks for your help.
