A revegged clone yield

I am a new grower and was reading that revegged plants have shit yields. Basically my clones from the dispensary flowered early. I put them out on (4/20/13) and within the last week they started to veg again. Am i going to have potential yield loss because of this?

Also ive read 24hr clones will flower anytime under 14.25hrs of light, is that true?

I was able to pull 2 lb's off a reveg. Revegging slows the plant way down and COULD affect yield if they don't bounce back quickly enough. I wouldn't give up on it at all.
