they both could could male or they both could be female....the fatter one is more of a indica pheno the other one sativaIs it maybe one is male one is female ?
That's how phenotypes work, it depends on the seed based on the parent's genetics.Mayb I'm crazy but these 2 plants grown from the same seeds look different to me, one more short n stocky(right one) the other more spread out and growing quicker ... Pics below
Both are about 3 weeks in.
Any insight would be appreciated
