light leak on day 1 flowering! help

I thought my room was light proof but I had a window leak some light on the first night of 12/12. Is there a good chance this will stress them enough to hermie?

I doubt it. The plant needs at least a few days, if not a week, to recognize the light cycle change. Seal up that window, and you should be fine.

Thanks for the help, I'm feeling a lot more confident now!
