the pitchers of my N. belli have been developing, but then the lids sink in. the light is fine as the plant is maroon in color, humidity is fine, soil is fine, etc etc. but why are the pitchers lids sinking in? i got the plant not long ago and both new pitchers it has produced are doing this, yet the plant doesn't seem to suffer any shcok from shipping or being transplanted and is growing rapidly.
any help? thanks
