Plagron PK 13-14 Flowering Booster

Concentrated Phosphorus and Potassium for Heavier, Denser Flowers

Plagron PK 13-14 is a mineral phosphorus and potassium booster for the flowering phase. Once a plant switches to bloom its demand for P and K climbs sharply, and most base feeds are formulated to cover the whole cycle rather than that peak. PK 13-14 supplies the shortfall directly, pushing energy into flower formation rather than foliage.

Key Benefits

• NPK 0-13-14 — pure P and K with no added nitrogen to prolong vegetative growth
• Denser, more compact flowers with noticeably better weight at harvest
• Accelerates fructification, driving the plant through bloom faster
• Highly concentrated at a 1:500 dilution, so a little goes a long way
• Works across every medium — soil, coco and hydroponic systems
• Mixes cleanly alongside any base nutrient range

Airy, Light Flowers That Never Fill Out?

Flowers that stay airy and light late in bloom usually point to a phosphorus and potassium shortfall at exactly the moment demand peaks. Running PK 13-14 through the flowering phase closes that gap, giving firmer, more solid flower structure and better final weight — without the excessive stretch extra nitrogen would cause.

How to Use

• Shake well before every use
• Add 2 ml per litre of water (a 1:500 dilution) during the flowering phase
• Add PK 13-14 first, then top up with base nutrient until your target EC is reached
• Use at every irrigation through bloom, not just as a one-off
• Always re-check pH and EC after adding — mineral boosters move both
• Pairs well with a carbohydrate additive such as Sugar Royal
