I planted a seed last week wednesday..everything was going great, but now i have 2 plants growing in one pot because 3 weeks ago i planted the same kind of seed and nothing grew. but it did grow and sprouted out of the soil 2 days after my other plant... should i remove this plant from the pot as soon as possible? the smaller one on the right is the one that finally sprouted after almost 3 weeks...the one on the left took only about 6 days to grow..
