It will reveg, which takes a lot of time. The buds should stop growing and the leaves will slowly start to grow. At the end of the Summer it should be back to good shape and start to flower up. You can feed and care for this plant and harvest a crop in the fall. I would cut the buds now, dry 'em and smoke 'em. It won't be much. Leave as much leaf material as possible and feed with a decent vegging plant food. Something with good percentage of nitrogen (the first number of the NPK). Maybe get it a little sister to grow with?
