The problem you are describing can happen for a few reasons but it is not uncommon in late winter when the hours of daylight have been short and not quite what the plant needs. It is a plant that likes bright but indirect light, though it can tolerate somewhat lower levels of light. If it is in a position that is just on the margin of what it needs during the growing season it may no longer be enough to allow the plant to thrive in the cloudy, low-light, short-day period of the year. It also needs to have a bit of a rest in the winter and to be kept at lower temperature, lower water and some supplemental humidity. Without the rest it can exhaust itself and decline.

Nudge it gently into a place with slightly more (filtered) light and resume your feeding program this month. A full care routine can be found in our Guide to Growing Pothos.
