Win the Mid-Bloom Window Where Flower Weight Is Made Monkey Nutrients PK 9/18 is a concentrated phosphorus and potassium bloom booster aimed squarely at the most demanding part of flowering. Once bloom is fully underway, plants need far more P and K than a standard base feed provides, and PK 9/18 delivers those ratios in a form that's easy to add alongside your existing bloom nutrients in soil, coco or hydroponic systems, driving heavier, denser flowers and stronger yields. Key Benefits High P and K ratio (9/18) targeted at peak flowering demand Increased flower density and overall flower weight Improved yield and stronger bloom development through mid-flower Stronger nutrient uptake during the demanding bloom stage Full harvest potential reached from your genetics All media: suits hydroponics, coco and soil Fixing airy flowers and disappointing flower weight? Without enough phosphorus and potassium through the middle of flowering, plants produce airy, loose flowers and lower yields than their genetics allow. PK 9/18 supplies the extra P and K exactly when flowers are being built, so plants channel that energy into thicker, denser flowers instead of stretching or running short in grow tents and controlled grow rooms. How to Use Dose: 2.5ml per 10 litres of water added to your nutrient solution Timing: use during weeks 5, 6 and 7 of flowering Method: mix thoroughly into the reservoir or watering container Alongside: run with your regular bloom feed in soil, coco or hydro Stop: discontinue before the final flush period Feed Chart Monkey Nutrients PK 9/18 · soil, coco and hydroponics, mid flowering Stage Per 1 L Per 10 L Flowering, weeks 5, 6 and 7 0.25 ml 2.5 ml Note — Monkey Nutrients publish this as 2.5 ml per 10 litres. Run alongside your regular bloom feed and stop before the final flush. Check pH and EC after mixing.
