It's a transition -- just like going from vege to bloom...
the hormonal balance is shifting ... if it got to "full bloom" and all vegetative growth stopped when you took it, it will take longer to re-vege than just the first few days of bloom light schedule
no biggie... if worht it.. stick with it, and when it does vigorously grow again (vegeatitively), it will be insanity for 2-3 week... explosive auxiliary growth all over.
