Double stems

[Mike666]

Hi all.
I germinated a GG auto and when roots started planted into pot.
It has 2 stems now showing, both with good leaf growth and looking like 2 plants close together.
I know I germinated only 1 seed.
This is my 4th plant from seed (new grower) and no idea what to do about this "double" ( if anything? ).
Any advice, comments excetera welcome.
thank you.
Mike.

Yes this happens breeding mutaition. One will survive while one needs to perish, just watch for what you think will be the strongest then snip off the weakest.
