An ideas what seedlings these are

[grimlyman]

These seeds I was given have a dark purple almost black stem and underside of leaves.

Dark purple almost black water leaves and stalk

Probably just genetics.
As to strain, no clue.

Well, she is alive.
Let her dry out a bit. It could be from overwatering.
What soil are you using?

 

[TheFertilizer]

There's a few "black" strains like that, Warlock, and Vietnam Black, but who knows what it is. Bagseed?

 

[grimlyman]

I'm not sure of their origin as to wether they were bag seeds, or from a hermaphrodite, but they are apparently fast growing and auto flowering. The dark will probably go away as they grow.
The first time I have seen seedlings that dark.
Any how thanks

If they do turn out to grow black, and one comes out male... seed it! I would go insane to get a black plant!
