What you're seeing is sooty mold. It grows on the excess nectar the plant produces. While somewhat unsightly, it doesn't really do anything to the plant, and can be wiped off with a wet paper towel or similar method.
It did come off fairly easily using a paper towel dampened with RO water. Happy that it comes off because it's rather unsightly :/ I didn't want to mess with the inside of the pitchers and inner hoods because I was afraid it would remove the nectar and affect it's ability to trap food so I left that be on all but the one I was cleaning when this dawned on me.
Now back to worrying about rather I can hack keeping my new regia alive lol. I've heard they are hard to keep and I've heard they are easy to keep but there is always grower error so I'm hoping it gets big and beautiful
