Lately I've been denying any Big Bloom in flower since I'm in FFOF which has the same organics in it. But when I was in other soil, I would stop the BB at the 4 week mark of an 8 week strain, and nothing but Tiger Bloom and mollasses till final dosing of Tiger Bloom at 6 or 7 weeks. Mollasses once a week and water as necessary from then till done.
