RETIRED - Liquid Fertilizer Concentrate 18-6-12 Water Soluble
18-6-12 Complete Has Been Retired
Over the past year, GrowScripts Complete 18-6-12 became one of our most popular fertilizers. However, some customers experienced caking and hardening issues during storage, particularly in humid conditions.
After reviewing customer feedback, we made the decision to discontinue the product rather than continue selling a formula that wasn't meeting our standards.
We are currently testing and evaluating the next generation of GrowScripts nutrition products, including new complete fertilizer formulations designed to improve stability while continuing to deliver complete nutrition for container-grown plants.
Thank you to everyone who shared feedback, photos, and suggestions throughout the process. Your input directly influenced the products that followed.
