Advanced Nutrients B-52 B-Vitamin Supplement 2-1-4

Help plants remain strong and productive through challenging growing conditions with Advanced Nutrients B-52. This concentrated 2-1-4 fertilizer supplement combines a readily available B-vitamin complex, kelp, humic acid and essential plant nutrients to support vigorous growth during both vegetative and flowering development.

B-52 is formulated to strengthen stalks, stems and developing flowers while helping plants withstand abiotic stresses such as transplanting, temperature fluctuations, drought, overwatering and salinity. Kelp helps fortify the root zone, while humic acid encourages microbial activity and assists nutrient uptake.

Compatible with soil, coco coir and numerous hydroponic systems, B-52 can be used with Advanced Nutrients pH Perfect base fertilizers, conventional base nutrients and other nutrient programs.

How to use:

Mix 2 mL per liter of water or prepared nutrient solution during the following stages:

Vegetative phase:

• Week 1: 2 mL/L
• Week 2: 2 mL/L
• Week 3: 2 mL/L
• Week 4: 2 mL/L

Bloom phase:

• Weeks 1–2: Do not apply
• Weeks 3–7: Apply at 2 mL/L
• Final flush: Do not apply

Always follow the feeding schedule appropriate for the crop, base nutrient and length of the growing cycle. Monitor plant response and adjust overall fertilizer strength when combining multiple supplements.

Foliar application:

B-52 is approved by the manufacturer for foliar use. Follow the current product label or Advanced Nutrients feeding guidance for the appropriate foliar concentration and avoid spraying plants under intense light or during late flowering.

Growing-system compatibility:

B-52 is suitable for regular soil watering, coco coir and continuous liquid-feed systems, including:

• Drip irrigation and emitters
• Deep water culture
• Aeroponics
• Nutrient film technique
• Flood-and-drain systems
• Other hydroponic growing media

Using B-52 with other Advanced Nutrients products:

B-52 is a biostimulant and nutritional supplement—not a complete base fertilizer. Pair it with an appropriate base nutrient and follow the Advanced Nutrients feeding schedule.

• pH Perfect Grow, Micro and Bloom: Supplies complete base nutrition while B-52 contributes B vitamins, kelp, humic acid and supplemental NPK.
• pH Perfect Sensi Grow and Sensi Bloom: B-52 can be added during its designated grow and bloom weeks without replacing either base component.
• pH Perfect Connoisseur: Compatible with this premium flowering base program when applied according to the scheduled rate.
• Voodoo Juice, Piranha and Tarantula: These microbial root-zone supplements complement the humic acid and root-zone support found in B-52. Follow the feeding chart to avoid unnecessary inputs.
• Rhino Skin: Supplies silica for additional structural support, while B-52 provides nutritional and environmental-stress support.
• Bud Candy: Provides carbohydrates during flowering and can be used alongside B-52 during overlapping scheduled weeks.
• Big Bud and Overdrive: These are stage-specific flowering supplements. Use each only during its designated bloom period rather than extending every additive throughout the cycle.
• Sensi Cal-Mag Xtra: May be added when calcium or magnesium supplementation is required. Monitor total nutrient concentration because both products contribute additional fertilizer elements.
• Flawless Finish: Discontinue B-52 and other fertilizers during the final flushing period before harvest.

Add B-52 to water or a prepared nutrient solution according to the feeding chart. Measure each concentrate separately and never combine undiluted nutrient products directly.
