Hi CJ,
Yes, I had a similar experience with one of my
N. x kuchingensis "Pink". I think the maturity and light will affect the coloration of the pitcher.
The 1st pitcher with nice pinkish lip
Subsequent pitchers with all pinkish pitcher after adapting to bright light.
A true "Hot Lip" - all pitchers will maintain the hot lip in different light level
Hope this help...
