Ionic PK 14/15 Bloom Boost Phosphorus Potassium Booster

Concentrated Phosphorus and Potassium for Peak Bloom

Ionic PK Boost is a PK 14/15 flowering supplement, a stronger concentration than the older Ionic Boost and applied weekly rather than at every watering. It supplies the extra phosphorus, potassium and iron that plants draw on hardest once flowers are forming and bulking. It works alongside any of the Ionic bloom base feeds, whether you run hydro, coco or soil, and will sit happily in nearly every mineral-fed system and substrate. It is not intended for organic feeding programmes. Available in 1 litre and 5 litre.

Key Benefits

• PK 14/15 concentration - a stronger ratio than the previous Ionic Boost, so less product goes further.
• Weekly dosing - one measured addition per week rather than a dose in every reservoir change.
• Iron included - supports the demand that heavy flowering places on iron as well as phosphorus and potassium.
• Works with any Ionic bloom feed - Hydro Bloom, Coco Bloom and Soil Bloom all take it.
• System agnostic - happy in nearly every setup, medium and mineral feed you are likely to run.
• Two sizes - 1 litre for a tent, 5 litre where several rooms are running.

Where Most Bloom Feeds Run Short

A base nutrient has to cover the whole flowering stage, which means it is never quite right for the middle weeks when flower bulking pulls hardest on phosphorus and potassium. Push the base feed up to compensate and the nitrogen goes up with it, which keeps the plant in leaf mode. A separate PK product lets you raise just those two elements for the weeks that need them, then step back down.

How to Use

• Add to the reservoir once a week alongside your usual Ionic bloom base feed.
• Dose into circulating water, never directly onto concentrated nutrient.
• Check EC after mixing and set pH last.
• Concentrate use through the flower bulking weeks and taper before flush.
• Do not use as part of an organic feeding programme.
