After the repotting and new environment stress, it initially lost all pitchers, but has formed new ones half a year ago. Now, it is thriving and still has the problem, that every pitcher has no digestive liquid inside, even when still closed.
From what I've read, they are about 1/3 filled when the lid is still on and that's where the juices are the most concentrated. But they should also be able to both form or suck up new liquid/ water, so even when some of it is lost somehow, it should be able to produce enough to digest prey, or if it "rains", they aren't diluted too much.
Well... mine are even "born" empty. The plant has a rough time catching flies on its own. They don't dry up and die or anything, they just are empty and unattractive for insects.
Conditions:
- Very high air humidity, most of the time about 70-80%. Again, I don't see any pitchers drying up all at once or any other issues. The plant is happy.
- Relatively high light. For houseplants very high. SW-facing huge window (northern hemisphere), but behind a curtain. Diffused. On sunny days, I get ~400 ppfd
- Substrate: LECA, semi-hydro
- Fertilizer in substrate: 1x every month or two 1 mS EC hydro nutrient solution, refilled with RO water. The EC is sitting at about 0,3-0,7 mS most of the time. I noticed much faster growth rates when fertilizing a bit, because in nature they are also getting some nutrients from the soil. But I keep it pretty low to encourage pitcher formation. I've seen a few yellowing bottom leafes (nitrogen deficiency) already, but they are relatively rare.
- Feeding: most of the pitchers are ignored from my side. I filled them up with said nutrient solution a while back from time to time, but I don't do that anymore, because there's enough active growth. One pitcher tho is filled with bugs I gave the plant, and when I see this pitcher dried up, I drop a bit of water in there to aid digestion. Just a bit, because in nature it probably rains in them too?

The oldest pitchers are getting consumed, but a lot of new ones are forming
Active pitchers, that have caught a few fungus gnats, and one that I used a while for active insect feeding
