That is the pitcher that was there when it was almost dead. :P This was the pitcher it made after repotting:How much light are you giving this? The adult pitcher is very flared, which is a sign of insufficient light. Maybe that's why it has reverted?
The immature pitchers are getting larger though, so I think it will start on the mature pitchers soon.
But anyway, it's growing under two t8 tubes, 32 watts I think.
