Humboldt Nutrients Big Up Powder 0-33-23

Humboldt Nutrients Big Up Powder is a high-phosphorus, high-potassium bloom finisher designed to maximize flower density and fruit weight during the final stages of the flowering cycle. The 0-33-23 NPK ratio delivers a concentrated P-K punch exactly when plants need it most — during the critical ripening and bulking phase.

Use Big Up Powder during weeks 6-7 of indoor and greenhouse flowering cycles. For outdoor flowering and fruiting crops, begin applications in late August as plants enter their final swell. This is not an all-cycle bloom nutrient — it is a targeted finisher that pushes weight, density, and essential oil production at the end.
