I have had a nepenthes for about a year now and i had it set up in a makeshift terrarium and sprayed water in there to keep the humidity high and it grew just fine. A few months ago I had decided to slowly acclimate it to life outside of the terrarium and took it out completely. The leaves have kept growing but the pitchers are not forming. A week ago I decided to set up a regular humidifier on a timer to get it up to the humidity level it needs. I dont see any growth difference but my ping seems to be doing better. Since I am bettering the conditions for it, will the old leaves eventually grow mature pitchers?

Pitcher growth is linked to light, humidity and available water (in my experience)to little of any can result in small or no traps, some of my nepenthes have taken up to 5-6months to pitcher again after they are hardened from my greenhouse to a tree in my yard (Townsville) and even then they produce small traps for the rest o their lives my Alata X maxima that's growing in Townsville outside is a couple years on and still making 14-15cm traps, but my greenhouse cuttings make 20-22cm traps, and the mother plant makes 25-27cm traps (this one is growing on a tree at dads near the rainforest), the only difference between the locations are humidity and a few degrees in temp (but not much).
However my mirabilis that I move outside are happy an making traps after just a month or two, this is because certain species will adapt faster/better than others, although the Maxima X alata is a hardier plant the mirabilis is a much faster grower/adaptor, for me at least.

I have never seen an already fully formed leaf produce a pitcher. It forms with enough humidity etc when the leaf is still developing. If it doesn't make a pitcher in this stage it won't do so later. You'll have to wait for new growth.

Nepenthes are tricky, they need long periods of adjustment to be successful in new environments. They are kind of like those "perpetual motion" clocks that run one the slight change in temperature in the air: you set them in a good spot, and then you don't touch them beyond the care they need. Plus, how old is the plant, and has it grown pitchers before?
