The phosphorus-potassium bloom enhancer that drives aggressive mid-flower development. One of the four core AN additives. Big Bud is Advanced Nutrients' phosphorus-and-potassium bloom enhancer, formulated to push more aggressive flowering response during the critical mid-bloom window. It's one of the four core AN additives we recommend running alongside the Sensi base, and it's the one with the most direct impact on flower development when timed correctly. The timing matters more than the dose with Big Bud. The P-K spike is most effective during week 3 of flower specifically, used as a targeted pulse rather than run continuously. Apply it during that mid-bloom window, then stop. Running Big Bud throughout flower wastes product and can throw off your P-K balance.
