Type: Mineral
Mineral feeds are dissolved minerals your plant can use straight away. They're fast-acting and precise, but it is possible to overdo them, so stick to the dose.

The Last Few Weeks Are Where the Harvest Is Made

There's a stretch late in flowering when plants stop putting on size and start putting on weight. Flowers fill out, fruit swells, and demand for phosphorus and potassium climbs higher than at any other point in the plant's life. Underfeed here and you'll never know what you missed.

IONIC PK is a concentrated phosphorus and potassium booster (PK 14/15) built for exactly those heaviest-demand weeks. Add it to your normal IONIC bloom feed and plants get the extra fuel they need to finish strong, without changing your whole feeding programme.

Why It Works

High-strength PK 14/15: concentrated phosphorus and potassium for peak bloom.
Denser flowers: supports flower size, density and fruit production.
Simple timing: one clear window, weeks 8–12.
Works with every IONIC bloom feed: soil, hydro, hard water and coco.

For Houseplant & Garden Growers

Tomatoes, chillies, peppers and strawberries all lean heavily on potassium and phosphorus once fruit starts to set. A small dose of IONIC PK in the watering can through the fruiting weeks helps them finish with bigger, better crops.

For Growers

Dose: 1ml/L.
When to use: weeks 8–12, the heaviest-demand flowering weeks, overlapping a week with IONIC Flower Boost.
Use with: any IONIC Bloom feed.

Rose's Pro-Tip: PK boosters are strong stuff. More isn't better: stick to the dose and add it to the tank separately, stirring before the next product goes in.
