If you grow cannabis, you’ve probably heard that phosphorus (P) and potassium (K) are the key to massive buds. That’s true — but only in the right amounts. Too much PK can actually do the opposite of what you want, stalling growth and reducing yields. Let’s break down why, and how Cronk Nutrients Bud Booster (0-1-3) keeps your plants in the sweet spot for big, healthy blooms.
The PK Myth
Many PK boosters on the market come with extreme numbers, like 0-50-30. On paper, it sounds powerful — but your cannabis plants don’t actually need that much.
Cannabis thrives with about:
-
Phosphorus (P): 20–60 ppm
-
Potassium (K): 150–300 ppm
Anything above these levels doesn’t “supercharge” your buds — it overloads the root zone. This can cause nutrient lockout, a condition where your plant can’t absorb other essential nutrients like calcium, magnesium, and nitrogen.
What Happens When PK Is Too High?
Overloading PK can lead to:
-
Burnt leaf tips and edges
-
Slowed bud development
-
Reduced terpene and resin production
-
Unbalanced nutrient ratios in your medium
Instead of boosting yield, high PK often creates diminishing returns.
The Balanced Approach: Bud Booster (0-1-3)
Cronk Nutrients Bud Booster is designed to give your plants exactly what they need — nothing more, nothing less.
With a 0-1-3 formula, Bud Booster delivers phosphorus and potassium in a range that encourages dense bud formation without overwhelming the plant. This keeps your flowers growing steadily, with strong aroma and resin production right through to harvest.
It works perfectly alongside your base nutrients, supporting:
-
Steady bud stacking
-
Healthy green foliage during flower
-
Strong stem and branch support for heavy colas
The Result? Bigger, Healthier Yields
By giving your cannabis the right balance of PK, you allow it to focus on building flowers instead of fighting nutrient stress. Bud Booster means more weight in your jars, better flavor, and smoother growing.
