Tell me about it Jay! I lost 2 clones and still don't understand why: I took a small cutting from each. The cuttings died, and the plants rapidly followed in their, errrr....wake. I had been keeping them very moist, and with phenomenal results. Then everything went sad and bad. The largest clone looked like it had a bad night with tequila out in the sissor factory. Everything I did after that was wrong: if I watered it it died more, if I didn't water it it died more. I reduced the humidity and it went downhill. I increased the humidity and the newest leaves withered and mold began to appear. I decreased humidity and increased water, and guess what? It died more. Finally, in a fit of pure spite, I encouraged the ravaged thing to die. I stuck it back where I wouldn't have to look at it's wastedness way back there on the shelf that just has only 2 lights and they weren't even above it. I kept it in the bin, but I put it in a smaller holeless container to keep it from the tray water so I could control the wetness and still keep it a little more humid with some air circulation. My memory didn't let me down: it was as good as ever, and I totally forgot about the plant. I happened to see it when I was getting ready for your visit (madly discarding ugly stuff, hee hee) and the pot was light as a feather (I use LFS as a medium) and BONE dry to the touch. Lo and behold, poking up out of this impossibly arid substrate were the first new pitchers: happy and bright green, and with vigorous new growth beginning on all the old brown and ruined stem heads. Like Tom Petty said "Even the losers get lucky sometimes".
My thoughts and conclusions: This species has a distinct seasonal rhythm. Wet is fine during the Aussie winter (our summer), and they respond. But there comes a time when the roots that grew so well in the wet season must cure and harden, and thats when they need aeration: this would be our winter. I think this is the case with many of the Australian tropical species: there is more than meets the eye with their culture despite their apparent lack of a need for dormancy. They continue to grow, sure, but in cultivation species like this often decline, and no one knows why. (e.g. The Queensland Drosera) It's because the rules changed, and we weren't aware that they did until the plants started dying back. My plants needed to slowly dry out more than I allowed them too. I assumed that because they were growing well in the conditions that I provided, that they would continue to do so which was an incorrect assumption in hindsight.
I think these plants always keep in touch with their distant home, and remain unconvinced with the seasons here. They grow best in our summer because they "think" it is the cool winter back home when they would grow best, and then they can't understand why it's so infernally hot! They want cool roots during their wet and active growing period, not a hot summer in the U.S. In our winter (their summer), they want more warmth, and less substrate wetness. Both these conditions require some effort for growers to provide in the relative seasons since neither are natural in most of the Northern hemisphere. I also believe it's true that they don't like to be disturbed. They're probably just too busy trying to convince themselves that they are back home down under.
