My first hamata is changing producing less curvy, larger and longer leaves. I had some trouble with it producing dud pitchers, proto-tendrils, at the end of the leaves that didn't extend and the tiny pitchers would turn brown. I traced it to lack of water, I guess I was over obsessing about doing something wrong. The clue was the greenery on the surface was developing brown patches so I paid closer attention by picking it up for a weight check more often.
My second hamata has slowed way down and just produced it's first dud pitcher. Everything is right so maybe it is just taking a break.
