as you are3 growing feminised Seeds, they all will be Girls....
and it depends waht you want to do with your plants... if you want multiple grow your girls as clones, you take the strongest as mother.
Or the ones that performs best.
But personally I wont give up on a plant that eraly....
Its often to see, that seeds from same package, perform different. But that has nothing to mean in this stage of grow
I often had surprises, brought by " the runtz of the litter"
