Pod Said that N is needed in qaulity at least for the first three weeks of flowering, than it can be phased out. Or something like that. The same I believe is the new idea of AN. Of course N must go totally out by the time you cut the plants, as the plant must be well flushed and N is the worst to be smoked. Isn't N anyway an important basis to make photosintesis?
My strategy will be to totally cut N in the last 3 weeks and I'll have to decide what to do before. If it wasn't I'm planning to use Bushmaster, which cuts a couple of weeks of strectch phase, I'd surely do three weeks of high N in bloom and then gradually phasing it out up to 0 for the 5th or 6th week depending on the plant.
