your plants could have come from a hermie plant.
they say from a hermie 50/50 females and hermies."from there seeds."
your plants could have come from the 50% hermie, and if so, 100% of your seeds could be hermie.
i would buy some more seed, its such a pain in the ass, when you have hermies, and a hermie will send all your females hermie too.
any pics of your plants?.
sorry to hear your having probs.
