Grow More® Sea Grow Bloom & Flower 4-26-26 — 25 lb

Kelp-Enhanced Low-Nitrogen Bloom Formula, 25 lb, for Maximum Flower Development

A synthetic high-PK bloom fertilizer supplies the raw phosphate and potassium flowering demands, but on its own it ignores the biological side of bud development. Grow More Sea Grow Bloom & Flower 4-26-26 combines that low-nitrogen, high-phosphate, high-potassium macronutrient base with botanical kelp extract carrying naturally occurring cytokinins and auxins, plus blood meal, amino acids, and organic carbon that support both the plant and the microbial life feeding it.

Available in 25 lb, the formula suits flowering vegetables, fruiting crops, and ornamental flowering plants grown in soil, coco coir, or hydroponic systems, and is most valuable from the onset of flowering through mid-to-late bloom.

Key Features & Benefits

• High-PK Bloom Profile (4-26-26): Low nitrogen keeps vegetative drive in check while high phosphate and potassium fuel energy production and flower site development.
• Botanical Kelp Extract: Cytokinins and auxins from the seaweed fraction support cell division and flower site development.
• Blood Meal Nitrogen Source: A naturally derived, slow-available nitrogen component that supports metabolic function without a sharp vegetative push.
• Amino Acids and Organic Carbon: Feed beneficial root-zone microbes and provide building blocks for protein synthesis during flowering.
• 100% Water-Soluble: Dissolves completely, compatible with drip, flood-and-drain, hydroponic reservoirs, and foliar spray.

Who Should Use This

Growers who want both a precision bloom-specific macronutrient formula and the biological benefits of a kelp biostimulant in one product are the direct fit, particularly for the mid-to-late flowering stage when phosphate and potassium demand peaks. It's often used alongside Sea Grow All Purpose 16-16-16 during the vegetative-to-flowering transition.

Frequently Asked Questions

How does Sea Grow Bloom & Flower differ from Sea Grow All Purpose?

Sea Grow All Purpose 16-16-16 uses a balanced ratio suited for vegetative growth and general feeding. Bloom & Flower 4-26-26 shifts to a low-nitrogen, high-P+K profile specifically for the flowering stage, when plants need more phosphate for energy production and more potassium for flower development.

When should I transition from All Purpose to Bloom & Flower?

Begin transitioning as the plant enters the reproductive stage, when flower sites become visible. You can switch abruptly or gradually blend the two formulas over 1 to 2 weeks to ease the NPK transition.

Does this formula contain enough calcium for flowering plants?

No, it's a macronutrient and biostimulant formula, and calcium and magnesium demand stays high through flowering. Supplementing with a dedicated calcium-magnesium product is recommended, especially in RO-water systems.

Can I use this for foliar feeding during flowering?

Yes, in dilute concentration during early-to-mid flower. Use caution with foliar feeding late in flower to avoid moisture accumulation on dense flower structures, and apply during low-light periods to minimize leaf-burn risk.
