HELP! Lights On and Off!?

Hey everyone,
I just picked up 7 Sour ol Grandaddy clones and I'm freaking out because the fluoros I had them under kept turning off and then back on. It did this probably for a total of 12 hours before I could do something about it. Also the clones were a week into flower when taking. So I'm getting all whacky thinking I stressed the shit out these plants and now I'm going to end up with nanners. Any opinions on whether my plants will be ok. I'm putting them on 24/0 to revert them back and hopefully get them back into gear. Please help me out!

give them time and they should be ok.

Don't worry about it they'll be fine, 12 hours of light going on or off isn't going to mess anything up.

OK good! Thank you guys for your replies. I just thought the cannabis plant was very sensitive to light but I'm glad it's not THAT sensitive. Thanks for the quick replies.
