Emerald Harvest King Kola PK Flowering Booster

More Flowering Sites, Heavier Blooms

Emerald Harvest King Kola is a bloom booster designed to bring the best out of plants through the flowering stages. It speeds the transition from veg to flower, increases the number of flowering sites and swells fruit, and it does that by supplying a concentrated hit of phosphorus and potassium along with nitrogen derived from hemp protein. The stretch between the last veg feed and full bloom is where grows lose momentum, and King Kola is aimed at it.

Key Benefits

• Faster veg-to-flower transition, so plants settle into bloom instead of drifting
• More flowering sites set across the canopy
• Extra phosphorus and potassium to power productivity through peak bloom
• Nitrogen from hemp protein, a higher-quality source than a plain mineral top-up
• Noticeable fruit swell in the second half of flower
• High-quality ingredients, part of the wider Emerald Harvest programme from California

Why Do Flowers Stop Filling Out?

Because demand outruns supply. In bloom, phosphorus and potassium requirements rise sharply while a base feed keeps delivering the same ratio it did in veg. The result is airy buds, slow growth in the last few weeks and low yields from a canopy that looked healthy throughout. King Kola raises PK availability at that point and adds hemp-derived nitrogen so leaves keep working rather than fading early, supporting nutrient uptake through to harvest.

How to Use

• Hydroponics and DWC: add King Kola to the reservoir after your base A&B, stirring between additions to avoid lockout.
• Coco: mix into the tank alongside your base feed and cal-mag, then feed as normal.
• Soil: apply as a root drench with your regular watering.
• Rates: follow the Emerald Harvest feed chart for your base series and week of bloom.
• Timing: begin as plants flip into flower and continue through peak bloom, stopping for your flush.
• pH after mixing: 5.8 to 6.2 in hydro and coco, 6.2 to 6.5 in soil.
