It needs more than 2-weeks to reveg a plant. it'll be about a month before you see the popcorn buds you left on it to start growing again(if it survives). When you cut allot off the top you suddenly have too much root for the plant. This often causes root-rot which will end your plant in short order. To reveg a plant is very tricky, it should be used to get clones of an awesome plant instead of for re-flowering(takes too much work).
Then re-flower after you've got all the clones you need.
