Autos shouldn't be affected by light leaks as they shouldn't be photosensitive. I've yet to have an autoflower plant hermie because I changed the hours of light. Sounds like bad genetics to begin with.
People asked if they are feminized seeds but you respond with "they are autos". There are regular autoflower seeds and there are feminized auto seeds. I am growing plenty of regular non-feminized autoflower seeds and currently pollinating all of them with a male autoflower plant pollen to make my own seeds.
