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

Balanced 5-5-5 Organic Feed with Calcium for the Full Growing Cycle

A fertilizer program built entirely around stage-specific formulas can leave a gap for growers who want one dependable, balanced feed to run for most of the cycle or to fall back on between transitions. Crown Jewels All Purpose Fertilizer fills that role with an even 5-5-5 NPK ratio plus supplemental calcium, giving plants balanced macronutrient support without favoring one growth phase over another.

The added calcium addresses a nutrient that's easy to under-supply in fast-growing indoor crops, supporting cell wall strength and helping reduce the incidence of calcium-related disorders, while the OMRI Listed and CDFA Approved certifications confirm it's compliant for certified organic growing programs.

Key Features & Benefits

• Balanced 5-5-5 NPK ratio — delivers equal nitrogen, phosphorus, and potassium for well-rounded nutrition across vegetative and reproductive stages alike.
• Supplemental calcium — supports cell wall development and helps reduce the risk of calcium-related deficiencies in fast-growing crops.
• OMRI Listed® and CDFA Approved — certified for use in certified organic production under both organizations' standards.
• Dry granular format — easy to measure and store, releasing nutrients gradually through soil biological activity and regular watering.
• Full-cycle use — suited to feeding throughout the entire growing cycle rather than one specific stage.

Who Should Use This

Organic growers who want a single, balanced fertilizer to run through most of the growing cycle, or to use as a steady base feed alongside stage-specific bloom or grow products, benefit from Crown Jewels All Purpose's even NPK ratio and added calcium. It suits both soil and soilless certified organic growing programs.

About Royal Gold

Royal Gold got its start roughly two decades ago as a small family operation in Humboldt County, California, and has since expanded its mixing, testing, and packaging operations to Upstate South Carolina. The company markets itself as the first nationally distributed coco-fiber-based potting soil company, and its Crown Jewels line extends that same small-batch approach into dry organic fertilizers.

Frequently Asked Questions

What does the 5-5-5 NPK ratio mean for my plants?

A 5-5-5 ratio means equal parts nitrogen, phosphorus, and potassium by weight, giving a balanced nutritional profile rather than emphasizing one macronutrient. That makes it suited to general feeding across multiple growth stages instead of one specific phase.

Why does this fertilizer include calcium?

Calcium supports cell wall structure and overall plant strength, and it's a nutrient that's easy to under-supply in fast-growing indoor crops relying only on a standard NPK blend. Adding it here reduces the need for a separate calcium supplement during general feeding.

Is this fertilizer suitable for certified organic growing?

Yes, it's OMRI Listed® and CDFA Approved, meaning it meets the standards of both the Organic Materials Review Institute and the California Department of Food and Agriculture for use in certified organic production. This makes Crown Jewels® All Purpose Fertilizer a reliable choice for growers maintaining organic certification throughout their operation.

Can I use this alongside Crown Jewels Bloom or Grow?

Yes, many growers use All Purpose as a steady base feed and layer in Bloom or Grow during their respective stages for extra stage-specific nutrition. Follow label application rates when combining products to avoid over-fertilizing.

How do I apply this granular fertilizer?

Work the granules into the top layer of soil or soilless media around the root zone, then water thoroughly to begin releasing nutrients. Reapply on the schedule stated on the product label, adjusting the interval slightly for larger containers or heavier-feeding crops.
