What do the numbers on the bottles mean?Updated 4 days ago

The numbers you see on each Cronk Nutrients bottle—like 6-5-4 or 2-1-6—show the ratio of Nitrogen (N), Phosphorus (P), and Potassium (K) inside the formula. These three elements are the primary nutrients plants need most:

• Nitrogen (N) helps plants grow tall, green, and leafy.

• Phosphorus (P) builds strong roots and fuels flowering.

• Potassium (K) strengthens plants and improves flower and fruit quality.

For example, Bonnie (6-5-4) contains more nitrogen for lush vegetative growth, while Clyde (3-6-5) has extra phosphorus and potassium to support big, healthy blooms.

The higher a number, the more of that nutrient the product contains. Use the right ratio for your plant’s stage—more N for veg, more P and K for bloom—and always follow the Cronk feeding chart for best results.
