This can, actually, be for several reasons. A photo will help me to make a better judgment call.
This can be due to over, or underwatering or due to a lack of light. Worst case scenario will be a fungal infection, but I'm hoping to rule this possibility out. If you can provide a photo I will be more than glad to help.
