As a result of this, their roots cannot handle minerals, they are specialized.
Someone else might know more about the light thing. I would continue giving it the same light for now while it recovers from the other stuff.
This seems like a pretty long thread already. If you're only asking why the ends of the tendrils are black and not forming pitchers, I can give you a few examples of why this sometimes occurs: 1) the tip of the tendril is too wet 2) it is too hot (like when touching lights) 3) it was physically damaged 4) there is a steady stream of dry air flowing past it 5) pests 6) dry media (although they usually don't turn black from this).
The plant itself looks pretty healthy to me, but all of the tips you've received thus far are generally important to consider. It will benefit the plant overall to implement all of them. If your water was too hard, you would see black tips on the sphagnum before the plant suffered from it, but it's still a good idea to know the salt content of your water.
Truth as Circe. Error has transformed animals into men; is truth perhaps capable of changing man back into an animal?
"soft" water frequently has sodium. Just be aware.

"Teaching a child not to step on a caterpillar is as valuable to the child as it is to the caterpillar."
Indeed. The things to look for are distilled or reverse osmosis, anything else has no meaning on the safety for carnivorous plants.
Everything has a reason, whether big or small. Never underestimate the power of what is or is not.
There is far more to everything than meets the eye.
Depending on levels of snow you get, you could scoop the top foot or so, but never anything by the road or the bottom three inches, into a bucket and use that for water in the winter. I break icicles off my house for water personally. You can make reverse osmosis water at home by boiling it, and somehow getting the steam into a colder room where it turns back into water.
