its up to you, its all up to your taste
Go ahead and trim off the dead ones, it'll make more room for new growth and allow more light to get to the green pitchers. Dividing depends on how far along in the growth season it is, I'm not sure what your weather is in ID, just dont divide during the peak growing times (mid-summer, early fall).
Well, should I cut off an entire pitcher for a little brown at the top? Or should I wait until it's all brown? None of them are 100% all brown...
That's up to you, I trim mine all the way down to the base even if the pitcher is not all brown yet. It'll take a while for the whole thing to turn brown. Even if the base is still green it wont do any harm to trim it off as long as your plant still has usable pitchers. Come winter and dormancy time you can trim them all off except for the phyllodias. The only exceptions are S. psittacina and purps.
My real problem right now is how slow it's growing. My previous few pitcher plants (which didn't survive the winter) were smaller, so I could really see new growth. That one's so big every once in a while I notice a new trap.
I'm thinking of doping it with some Dried Bloodworms, that might get it a little bit of kick. I did notice it caught a few bees on it's own, though, so maybe that's overkill.
I took the VFT "Gold Stirke" and my VFT Typical outside, and am going to replace the Dente and Akai Ryu "real soon now" (tm).
I hate to do it, but, yeah, the VFT Gold Strike needs to get bigger and I think pure sunlight will help with that more than growlights. I did notice it had 2 growing points so I cut one off and put it in my prop chamber, hope it survives. The one outside has more green than the one inside.
It might be about time to look at a RO filter, heh, I'm going through a lot of water nowadays.
