One of the four seeds same strain is having different sprouting speed than the other three, still struggling to make it while the other ones already grew 4 cm first four days.
In my last grow i had 2 of these, both topped themselves and hat some strange anomaly's.
They caught up in growth and yielded as good as the others.
Why don't you keep that 1 AND plant 1 extra 😎
Good luck,
