Crown Jewels® All Purpose Fertilizer 5-5-5 + Calcium 1lb

Crown Jewels® All Purpose Fertilizer 5-5-5 + Calcium 1lb — OMRI Listed Organic Granular

Crown Jewels® All Purpose Fertilizer by Royal Gold LLC is a premium dry organic granular fertilizer featuring a balanced 5-5-5 NPK ratio plus supplemental calcium, certified OMRI Listed® and CDFA Approved for use in certified organic growing programs. Designed for use throughout the entire growing cycle, the balanced nutritional profile supports healthy vegetative development, structural integrity, and sustained plant performance without the nutritional imbalance that can result from stage-specific fertilizers used exclusively throughout a grow.

The addition of calcium alongside the balanced 5-5-5 NPK ratio makes this an excellent choice for growers who want to address potential calcium deficiency alongside primary macronutrient nutrition — supporting robust cell wall development and reducing the incidence of calcium-related physiological disorders in fast-growing indoor crops.

Key Features & Benefits

• OMRI Listed® & CDFA Approved: Certified for use in organic production by both the Organic Materials Review Institute and the California Department of Food and Agriculture, providing growers with verified compliance for certified organic programs.
• Balanced 5-5-5 + Calcium NPK: The equal-ratio NPK formula with added calcium provides comprehensive primary macronutrient support across all growth stages, with calcium supplementation to support structural development and reduce deficiency risk.
• Dry Granular Format: Easy to measure, store, and apply. Granular dry fertilizers release nutrients through soil biological activity and watering, providing sustained nutrient availability over time in soil and soilless growing media.
• Organic Nutrient Sources: Formulated from certified organic raw materials that support both direct plant nutrition and beneficial soil microbiology, promoting a healthy and biologically active growing environment.
• Versatile All-Stage Use: The balanced NPK ratio makes Crown Jewels® All Purpose appropriate for use from vegetative growth through the early stages of flowering, providing a simple and consistent organic feeding foundation.

Frequently Asked Questions

What does "5-5-5 + Calcium" mean on the label?

The 5-5-5 refers to the NPK ratio — 5% nitrogen (N), 5% phosphorus (P₂O₅), and 5% potassium (K₂O). The "+ Calcium" indicates the inclusion of supplemental calcium in the formula, which supports cell wall development and helps prevent calcium-related deficiency disorders.

Can I use Crown Jewels® All Purpose throughout the entire grow cycle?

Yes. The balanced 5-5-5 NPK ratio is designed for versatile all-stage use. Many growers use it as a foundation fertilizer throughout the grow, supplementing with Crown Jewels® Bloom or Imperial Boost during the flowering phase for stage-specific nutritional support.

Is this product suitable for hydroponic systems?

Crown Jewels® All Purpose is a dry granular organic fertilizer most suited for soil and soilless media growing environments where biological nutrient cycling can occur. It is not designed for use in recirculating hydroponic systems where undissolved particles can cause system issues.

How is a dry granular fertilizer applied?

Dry granular fertilizers are typically worked into the growing medium at transplant time or top-dressed around established plants, then watered in. They release nutrients gradually as they are broken down by microbial activity and water. Follow label directions for specific application rates.

What are the OMRI Listed® and CDFA Approved certifications?

OMRI Listed® means the product has been reviewed and approved by the Organic Materials Review Institute for use in certified organic production under the USDA National Organic Program. CDFA Approved indicates approval by the California Department of Food and Agriculture for organic use under California regulations. Together, these certifications provide high confidence in the product's organic status.
