Question would be,.. How long into flower are you?

I'd think that getting a plant to go out of flower is harder then getting it into flower. If your early on, might not be a big deal. If your later in it might cost you some yield but should be ok.

Beings that the 12 off, just allows the hormones that cause a plant to flower to build up. Even a couple days without doesn't make them dry up and fall off. It just doesn't put all of it's energy into the flowers until that hormone builds up again.

Although just an educated guess. More info on how far along you are, and what kind of light are you using might help too.
