assuming you started from seed it would most likely be too early to tell. also if you see hermie traits you might want to consider which is more dominant, m or f. dominant females can turn out nicely provided their is no added stress and you dont mind some seeds in your other plants. if you have clones its still a bit early im guessing. be patient until youre sure, then discard as needed and bitch at your scource. stress will invite hermies so look at your operation to see if thats an issue.
