Is there something wrong with this lowii?

This is a be3100 from carnivero. Has anyone else had experience growing this plant? Ive had it for about 10 months and it’s gained size since I first bought it, but the pitchers aren’t looking right anymore. It been getting temperatures of between 82-86 in the daytime and then 58-62 at night, with daytime humidity 70-78 and night time humidity 82-88. Is it a picky plant? Does it like strictly highland conditions? Can anyone with experience growing this plant chime in on what I may be doing wrong?
