Grow More® Sea Grow Bloom & Flower 4-26-26 — 5 lb

Kelp-Enhanced Low-Nitrogen Bloom Formula, 5 lb, for Maximum Flower Development

A straight synthetic bloom booster covers phosphate and potassium but skips the biological side of flowering. Grow More Sea Grow Bloom & Flower 4-26-26 pairs a low-nitrogen, high-P+K macronutrient profile with botanical kelp extract, blood meal, amino acids, and organic carbon — delivering the energy production and structural development flowering demands alongside the biostimulant activity that supports fuller flower development.

The 5 lb size fits growers who want that combined synthetic-and-biological approach at a mid-range volume, suited to soil, coco coir, or hydroponic flowering programs.

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 organic building blocks for protein synthesis during flowering.
• 100% Water-Soluble: Dissolves completely with no residue, compatible with drip, flood-and-drain, hydroponic reservoirs, and foliar spray.

Who Should Use This

Growers who want both a 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.

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.
