Hi Anson,
I don't think we'll be able to help you much unless you
tell us more about your plant, and the conditions under
which you are keeping it. Tell us about the temperature
range in its environment, the number of hours of light it
receives, (as well as the light source) the relative humidity
in the area, the compost, and how often you are watering it.
Also, is the plant otherwise healthy? At what point in the
process of producing pitchers does pitcher formation cease, etc?
If you can tell us about these things, or at least some of them,
then someone here should be able to help you.
