Lights Out for 24 Hours during Flowering

My Quamtum 600 dig. ballest blew. My lights have been out for 24 hours, how will this affect my plants? 2nd week of flower.

It is tough to tell you a definitive answer on this because nobody can really tell you the future. As long as it was only once you should be fine, they are going to be stressed so keep an eye out for hermie's through your grow. GL brotha!

Nope, it shouldn't. If they had been 'on' you would have had a big problem, darkness usually isn't a big deal (for short periods of time).
