VitaLink PK 1L – High-Phosphorus & Potassium Flowering Stimulant

VitaLink PK is a highly concentrated phosphorus and potassium flowering stimulant designed to give plants an extra push during their peak flowering period. By increasing the P:K to nitrogen ratio at the critical stage, it supports exceptional flower and fruit development in size and quality.

How It Works

Phosphorus supports key metabolic processes including photosynthesis, energy transfer, and carbohydrate synthesis. Potassium — often called the “quality nutrient” — influences the shape, size, colour, and taste of flowers and fruits. Together in an ideal ratio, they redirect plant energy towards reproductive development at the moment of highest demand.

Key Features

• Highly concentrated P:K stimulant for peak flowering
• Increases phosphorus and potassium to nitrogen ratio for superior flower and fruit development
• Readily available nutrients in an accessible form for fast uptake
• Ideal for use in all growing systems and media (soil, coco, hydroponics)
• Use in place of VitaLink Buddy during the week of highest demand

How to Use

• Dose: 1ml per litre alongside your main nutrients
• Use during the week of peak flowering only
• Do not use simultaneously with VitaLink Buddy – swap PK in during peak demand
• Recommended pH range: 5.8–6.5
• Shake well before use
