Hey all, Forgive me if this is a newbie question Why not use something like KoolBloom powder instead of Bud Blood/MoaB in the first 2 weeks of flower? The products are both high in PK - so what is the difference? Ingredients: BudBlood: Potassium sulfate, potassium phosphate and magnesium phosphate. MoaB: Potassium Phosphate, Ammonium Phosphate Open Sesame: Ammonium Phosphate, Potassium Phosphate, Potassium Sulfate (+other ingredients) VS late PK booster like KoolBloom: KoolBloom: Ammonium phosphate, ammonium sulfate, potassium phosphate, potassium sulfate and magnesium sulfate. I underlined the common ingredients to highlight the similarity. I'm particularly interested in people's past experiences with this, if you have any. Have you tried this before?
