Can I use Cronk Nutrients on any type of plant?

The numbers on Cronk bottles are N-P-K ratios—nitrogen for green growth, phosphorus for roots and flowers, and potassium for plant strength and yield.

The numbers you see on each Cronk Nutrients bottle&#x2014;like 6-5-4 or 2-1-6&#x2014;show the ratio of Nitrogen (N), Phosphorus (P), and Potassium (K) inside the formula. These three elements are the primary nutrients plants need most:<ul style=" text-decoration: none;"><li>Nitrogen (N) helps plants grow tall, green, and leafy.</li><li>Phosphorus (P) builds strong roots and fuels flowering.</li><li>Potassium (K) strengthens plants and improves flower and fruit quality.</li></ul>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&#x2019;s stage&#x2014;more N for veg, more P and K for bloom&#x2014;and always follow the Cronk feeding chart for best results.
