man... been there, I had a straight female... nothing but pistils at every node, I grew this fukn transsexaul bitch for 5-6 months screen style, it was about 3x3 with 6-8in tops everywhere when I put it into flower, I must have put over 100 hrs into that fuker,,,, 5 weeks later... u guessed it fukn balls and nutz popping out everywhere.... that was 3 yrs ago and it still pisses me off, lol.. I stoped growing that strain all together.... thAt is such a bitch!!
But I have to add, make sure its more than one branch or more than a few nodes, I have had fems pop out like 4-10 balls and still bud up fat and chunky. some strains will drop a few bannas normally, these are actually female pollen sacks and will give you female seeds with the trait of hermie, nothing to breed with for the long term but, I got a harvest of fem seeds, grew them out and yeilded like 12oz off 15 plants. So just make sure its all over the plant before you kill it!!
