Nepenthes no longer producing pitchers

Not sure, when nep's don't pitcher, the first thing is usually the light is too low... This species, if it is hirsuta, is an intermediate. It likes it warm during the day and a little cool at night.

On the other hand, it might not like the vermiculite.

I wouldn't describe N. hirsuta or N. hispida as beginner plants, they can be temperamental. Perhaps, repot it into a soil with sphagnum, perlite, cedar mulch (remove any large pieces) and a little peat moss. A small pinch of limestone wouldn't be a bad idea either.

I would also add it doesn't need misting in a terrarium.

I don't know whether the reason of no pitchering is due to the use of MaxSea. In another forum, some people say the result of MaxSea is crazily growing leaves but no pitchers, similar as you described ("growing leaves like crazy but the pitchers shrivel up and fall off"). There is a hot argument on the use of MaxSea. Some people also say the use of MaxSea has best result (induce pitchering). For me, I apply the MaxSea only on those very tiny nepenthes, because I hope the young neps grow quickly, and I don't care about whether they pitcher. But I never use the MaxSea on those big neps which have showed beautiful pitchers. Since I've used the MaxSea for only 1 month, I can't tell whether it induces pitchering or not. I can only say that it is very good for the growth of young neps. My suggestion is: if the above people's suggestions do not work (such as increase the light), then stop the use of MaxSea or reduce the strength of MaxSea and see the result.

If the plant starts to pitcher in the future, come here to tell us what you do for it.

I have diluted down to the recommendation for CPs, 1 teaspoon per gallon and mist the surface of the leaves with it ever two weeks. I guess I'll transplant and cut off the fertilizer to see if it starts pitchering again.

Thanks, I'll try to take some clearer pictures on the weekend and post again. I repotted in a mixture of perlite, peat, a little spaghnum, charcoal and sand (all I could get locally here in Yokohama). The thing looks incredibly healthy, just no pitchers.

This is a link to some recent photographs I took. I've had the terrarium covered and more humid in the last few weeks and am hopeful this will encourage pitchers, plus as you say it is warmer here especially in the summer. Thanks for all the advice! I did attach one photo here that shows an older pitcher; perhaps this will aid identification

Well, it isn't any species is the insignis group... You'll have to let it grow out some more so it can develop some diagnostic features for an ID.
