I have a pothos and a curly leaf philodendron vine that are not thriving, despite getting water, adequate light and fed every two weeks. I am at loss as to what to do...small leaves, and little growth. Can they simply be "old"????

It is likely that they are being over-fed. Both of these are low-feeding, and will only require fertilization every few months. Let the soil get a little dry in between waterings, as well. Extra fertilization may have thrown the pH of the soil off. Add dolomitic lime to the soil around, and it will break down as you water. This helps control pH of the soil.
