Hello. This is a big question for me. I have found bananas and seeds in my flowers before but it was caused by a light leak. Since that time I have light proofed the room plus the plants are grown in tents. So it's definitely not a leak. My ballasts sometimes do not start on time, but they turn on within 15 minutes. So I don't know if the 15 minute delay would cause the hermaphroditism. I have also considered bad genetics as the cause, but I am only using non-feminized seeds from a well known breeder. Thanks.
