Royal Gold Crown Jewels Bloom 1-4-2 | 40lb

Bloom-Optimized 1-4-2 Organic Fertilizer for Flowering, 40lb

Nitrogen needs typically drop once a plant shifts into flowering, while phosphorus and potassium demand climbs to support bud initiation, flower development, and fruit set. Crown Jewels Bloom is formulated around that shift with a 1-4-2 NPK ratio, keeping nitrogen low while delivering the elevated phosphorus and potassium the reproductive stage calls for.

This 40lb bag suits commercial growers feeding larger container counts or in-ground beds through a full flowering and fruiting cycle, without the smaller case packaging of the 5-20lb sizes.

Key Features & Benefits

• Bloom-optimized 1-4-2 NPK ratio — reduces nitrogen relative to phosphorus and potassium to match the nutritional shift plants undergo during flowering.
• Elevated phosphorus — supports energy transfer, bud initiation, and root activity during the high-demand bloom phase.
• Enhanced potassium — drives sugar translocation and carbohydrate accumulation for stronger flower and fruit development.
• OMRI Listed and CDFA Approved — certified for use in certified organic bloom and fruiting programs.
• Dry granular format — easy to measure and apply, with nutrients released gradually through soil biological activity and watering.

Who Should Use This

Organic growers whose plants have entered the flowering or fruiting stage, and who want a low-nitrogen, phosphorus- and potassium-forward fertilizer to support that transition, benefit from Crown Jewels Bloom. It's suited to certified organic programs in both soil and soilless growing environments.

About Royal Gold

Royal Gold began nearly twenty years ago as a small family operation in Humboldt County, California, later expanding its mixing and packaging operations to Upstate South Carolina. Known for pioneering nationally distributed coco-fiber-based potting soil, the company applies the same small-batch quality standard to its Crown Jewels dry fertilizer line.

Frequently Asked Questions

Why is nitrogen lower in this bloom formula?

Excessive nitrogen during flowering can suppress bud development and push plants toward continued leafy growth instead of reproductive output. Crown Jewels Bloom's 1-4-2 ratio dials nitrogen back so phosphorus and potassium can do the heavy lifting during this stage.

When should I switch from Crown Jewels Grow to Crown Jewels Bloom?

Switch once your plants show clear signs of transitioning into the flowering stage, typically indicated by the appearance of buds or flower sites. Following your specific crop's known flowering trigger, such as a shortened light cycle for photoperiod plants, helps time the switch accurately.

Is Crown Jewels Bloom certified for organic growing?

Yes, it's OMRI Listed and CDFA Approved, meeting the requirements of both the Organic Materials Review Institute and the California Department of Food and Agriculture for certified organic production. This certification lets certified organic growers apply Crown Jewels Bloom through the flowering stage with full compliance confidence.

Can I use this together with a PK booster like Imperial Boost?

Yes, many growers layer Crown Jewels Bloom as a base bloom feed and add Imperial Boost during the late-bloom push for extra phosphorus and potassium. Follow the label rates for both products together to avoid over-fertilizing.

How do I apply this granular fertilizer during bloom?

Work the granules into the top layer of soil or soilless media around the root zone at the start of the bloom stage, then water thoroughly. Follow the reapplication interval on the product label, timing subsequent feedings to the crop's bloom-stage progress.
