Droopy Paph. Concolor

[Chris147]

I bought a paph. concolor over the weekend, and the guy told me that the yellow growth was dying because it was old and that the new growth would toughen up. I have noticed that most of the plant is droopy. What is wrong with this plant? I can't get a refund because the man told me that he didn't know how I was taking care of the plant. I have also noticed that the leaves are really thin anf flimsy. Why is this? I watered today because it looked dry and the pot was light. I let it soak for about 5 minutes just in case the plant hadn't been properly watered in the hot greenhouse. Thanks in advanced for any help.
