I'd love to follow the grow log for that! If I were doing it I'd wait til the usual time for giving it nutes, probably with half veg and half bloom, and do that for at least a couple weeks before switching to all or 3/4 bloom nutes.
Before flushing it should be fine for all bloom.

Would like to try that method one day, but maybe after I make some feminized seeds.

Good luck with it
