Sounds like the description of the Drosera leaves are correct,
but you should be able to see the glands under high humidity as this
is noticeable from the first leaves. If not, then they're weeds of some
sort. Most Drosera look similar during their first weeks of life.
The ping I can't really say, but it does sound like it's a weed.
The Sarracenia description is correct for plants about that
age. The tall skinny leaves are the cotyledons and you're right,
the one being formed in the middle will be the first tiny pitcher.
Hope that helps.
Happy cping,
Chris
