PK 4/10 (2-4-10)
Creates bigger and heavier blooms of superior quality
Advanced Nutrients Hammerhead is the modern alternative to the standard PK type flowering boosters available today. PK-type boosters were originally designed a long time ago for agricultural outdoor use where phosphorous is quickly washed out of the soil. With indoor growing this does not happen and so the ideal ratio of P to K is different. Advanced Nutrients have formulated Hammerhead to have the ideal ratio of P to K for indoor gardening. Hammerhead provides exactly the right amounts of supplemental P and K for optimal bloom boosting without over-fertilising or burning your plants. Hammerhead also contains various other ingredients that your plants require a lot of during peak-blooming such as magnesium that other PK boosters do not contain. Try Hammerhead instead of your usual PK booster and then see, smell and weigh the difference in your crops.
Use 2ml per litre of water. Use in weeks 2-6 of flowering stage.
