PK 13-14 is a classic bloom booster designed to supercharge cannabis plants in late flowering. High in phosphorus and potassium, it increases bud density, improves flower structure, and enhances resin production. Easy to mix and compatible with any nutrient line, it gives your plants the final push needed for maximum yield. Apply during peak bloom to see real weight stack onto your colas. It’s a no-nonsense, proven additive that brings solid results. Bigger buds, thicker resin — it’s that simple. For excellent bud development, combine PK 13-14 with the nutrient line of your choice, such as Cocos A and Cocos B, or Hydro A and Hydro B.
