Athena PK - Blended Line

Denser flowers and richer terpenes without the lockout risk

Athena PK is a precision liquid bloom booster for the mid-to-late flowering phase, when plants call for extra phosphorus and potassium to bulk out flowers and build resin and essential oils. Unlike PK additives that dump in raw P and K and trigger lockout, Athena PK carries a balanced P:K ratio that lifts bloom performance without crowding out calcium and magnesium uptake. It's fully soluble, sediment-free and compatible with every fertigation system.

Worried a PK booster will cause lockout instead of bigger flowers?

Oversupplying phosphorus and potassium is a leading cause of calcium and magnesium deficiency late in flower, showing as leaf curl or weak flower structure right when you need bulk. Athena PK's balanced ratio boosts flower and fruit density while leaving the rest of your feeding programme intact.

Key Benefits

• Boosts essential oils and terpenes - improves flavour, aroma and overall crop quality
• Increases flower and fruit density - drives larger, heavier yields at harvest
• Balanced P:K ratio - bulks flowers without compromising Ca/Mg availability
• Clean, sediment-free formula - compatible with drip systems and automated irrigation
• Versatile across media - works in coco, hydro, rockwool or soil

How to Use

• When to run: introduce from the mid-flowering stretch through to late flower, alongside your base feed
• Dose to the chart: follow Athena's Blended Line feed chart for your stage and system, adding PK to the reservoir with your base rather than on top of a full-strength feed
• Introduce gradually: ramp up over a few feeds and monitor plant response, adjusting EC as you go
• Set pH: hold pH 5.8-6.2 in hydro and coco after mixing
• Taper: ease off into your finishing / ripening period
