Usually dying pitchers and problems in developing new ones is either
a problem of light or humidity. If your plant was doing fine and now
has problems without any change of growing conditions a root damage
is very likely (=> The plant is water stressed because it cannot get
the water from the soil anymore). Try to check the roots. If they are
dead, cut the dead ones away and theat your plant like a cutting.
Keep in mind, that Nepenthes have black roots and a yellowish tip if
the roots are OK. You shold look for this tip. If the root is
completely black including the tip, it's dead.
