this is very true.look at the top nodes they will show there first.The males usually show their sex before the females do... so maybe the rest of them are females.
thats what I'm hoping with my current grows from bagseed. So far I have found no males. 5 females out of 19 so far. I'm waiting to see what the others do and the best will stay. From what I can see I have 4-5 dif strains going. All of them were from smoke that was definitely above average, and not the kind you'd expect to see seeds in.The males usually show their sex before the females do... so maybe the rest of them are females.
