urgent help needed

for some reason the power to my grow room went out and im not exactly sure how long my babies were in the dark but im pretty sure it was 12 hours plus. I planted them on april 1st.

A 12 hour break in the light cycle of 5 week old plants should not be a big deal. If they are back on their normal schedule, they will be fine, just a soon forgotten bump in the road.
Good luck & good grow.......BB
