IONIC PK BOOST 1 LITRE

Description

Ionic PK Boost 1 Litre is a concentrated phosphorus and potassium additive from the Ionic nutrient range, designed to supplement the phosphorus and potassium requirements of flowering plants during the peak bloom stage when elevated PK demand exceeds what a standard base nutrient can optimally deliver. We have been recommending Ionic nutrients and additives to UK growers since 2017 as a straightforward, well-formulated British nutrient range that delivers reliable results without unnecessary complexity, and PK Boost is the targeted flowering additive that completes the Ionic programme.

Why Elevated PK Is Essential During Peak Flowering

As plants move through the flowering stage, their metabolic priorities shift from the nitrogen-heavy demands of vegetative growth toward the phosphorus and potassium requirements of flower development. Phosphorus drives the ATP energy transfer that powers rapid flower cell division and the biosynthesis of the aromatic and resinous compounds that determine harvest quality. Potassium is the primary driver of sugar translocation — the movement of photosynthetically produced sugars from leaves to developing flower sites that directly determines flower bulk and density. During the peak bloom weeks — typically weeks 4–7 of an 8–10 week flowering period — these demands are at their highest, and a base nutrient alone may not fully meet them without pushing EC to levels that create stress. Ionic PK Boost provides a targeted phosphorus and potassium top-up that meets peak demand without creating the elemental imbalances that can occur with less precisely formulated PK products. The Ionic formulation is calibrated to be compatible with the Ionic base nutrient range and to integrate cleanly with both coco and hydroponic systems.

How to Use Ionic PK Boost in Your Flowering Programme

Introduce Ionic PK Boost from week 3–4 of flowering at 1–2 ml per litre, increasing to 2–3 ml per litre through peak bloom weeks 4–7. Taper and discontinue in the final 1–2 weeks before flush. Always add to your base nutrient solution after the A and B components, then check and adjust pH to the target range for your growing medium. Monitor EC after all additions and adjust base nutrient dosage downward slightly if total EC exceeds your target range. Compatible with all Ionic base nutrients and growing media.
