The pitchers indicate a problem with insufficient lighting. The nectar spoons are underdeveloped and there is virtually no red coloration. Can you move the pots closer to the lights (4-6 inches away)? In addition, your soil mixture may be too dense. I've had good success with a 50/50 mixture of dried LFS and perlite.
Up until two years ago I grew heliamphora under lights in my basement. I've since switched to growing them on a south facing windowsill, resulting in healthier plants. The sill receives 5 hours per day of direct sun during the summer. I've supplemented their lighting with two desk lamps, each having a 100 watt fluorescent bulb.
