well, for what its worth, my purple urkle came from some bud I got from medical dispensary. about 15 seeds in the eighth and they all came out females except one. it just means that they will be much more prone to go hermie if they are induced to stress. they are many things that can stress the plant, and the light leak you explained would do it. it doesn't take much for some strains while it might take a shit load of stress for another strain. that being said, with your seeds coming from bud, it probably won't take much

I thought you were running some high grade seeds too? well anyways if these are all the same seed, you have 2 choices. scrap em and get some good genetics or ensure that they will see no more stress (the non herm ones) and hope they turn out female
