Targeted Flower Booster for Coco Coir Grows

Big Bud COCO 10L is a specialised bloom enhancer formulated by Advanced Nutrients to deliver explosive flower development in coco coir systems. This coco-specific version of the classic Big Bud contains optimal ratios of phosphorus, potassium, magnesium, and amino acids, ensuring your plants receive everything they need for bigger, heavier, and more resinous blooms—without nutrient lockout.

What sets this formula apart is its addition of extra magnesium and calcium-binding agents, which directly address the unique nutrient-holding characteristics of coco substrates. This prevents common deficiencies and ensures consistent nutrient availability during the critical mid-bloom phase.

Ideal for professional growers and hobbyists alike, Big Bud COCO boosts bud size, aroma, and essential oil production for higher-quality harvests.

Key Features:

• Volume: 10L – ideal for medium to large grow operations

• Coco-Specific Formula: Added magnesium and chelation agents to support coco coir

• Enhanced PK Ratio: Optimised for mid to late flowering stages

• Supports: Bigger blooms, higher yields, and enhanced terpene profiles

• Compatible With: All coco-based hydroponic systems and feeding schedules

• pH Perfect Technology: Stabilises nutrient pH automatically (when used with compatible Advanced Nutrients products)

• 1 x 10L bottle of Big Bud COCO liquid flowering booster

• Measuring instructions on label

• Resealable container for clean, long-term storage

Use Big Bud COCO during weeks 2–4 of the flowering stage, at a rate of 2ml per litre of water. Shake well before use and mix into your nutrient solution after base nutrients but before pH adjustments (unless you’re using Advanced Nutrients’ full pH Perfect line).

This formula is best used alongside other Advanced Nutrients Coco products, such as Sensi Coco Bloom A&B, for a complete and balanced feed. Monitor your EC levels to avoid overfeeding in sensitive strains, and ensure regular runoff in coco coir to prevent salt build-up.

Store in a cool, dark place, and avoid contamination by using clean measuring tools.
