Advanced Nutrients Kushie Kush® 1-3-8 Bloom Booster

Advanced Nutrients Kushie Kush® is a concentrated 1-3-8 bloom booster formulated for the flowering stage, with a potassium-forward nutrient profile developed with Kush varieties in mind.

Rather than relying on an extremely high-phosphorus formula, Kushie Kush supplies both phosphorus and potassium with considerably more soluble potash than available phosphate. This targeted PK profile makes it a specialized flowering supplement for growers looking to support productive flower development during the critical early-to-mid bloom period.

The Canadian formula is registered on the label for use on herbaceous plants, including cannabis.

Why Use Kushie Kush?

Kushie Kush was developed by Advanced Nutrients as a dedicated bloom booster for Kush varieties and Kush-influenced genetics.

Its 1-3-8 analysis provides a modest amount of nitrate nitrogen along with phosphorus and a substantial concentration of potassium. During flowering, these nutrients support the plant's increased nutritional demands as it transitions from vegetative growth into flower production.

Unlike many traditional bloom boosters that place extremely heavy emphasis on phosphorus, Kushie Kush has a distinctly potassium-forward 1-3-8 formulation.

Key Features

• Specialized flowering-stage nutrient supplement

• 1-3-8 guaranteed analysis

• High-potassium PK formulation

• Developed with Kush varieties in mind

• Provides nitrate nitrogen, phosphate and soluble potash

• Derived from monopotassium phosphate and potassium nitrate

• Suitable for herbaceous plants, including cannabis, according to the Canadian product label

• Can be used with nutrient solutions, coco and other growing substrates

• Concentrated application rate of only 2 mL per litre

Guaranteed Analysis

Derived from: Monopotassium phosphate and potassium nitrate.

Directions for Use

Shake well before use.

Use 2 mL of Kushie Kush per litre of water during weeks 2 through 4 of the bloom phase, based on an 8-week flowering cycle.

Irrigation Frequency

Nutrient Solutions: Mix a new reservoir weekly.

Coco: Apply daily.

Other Substrates: Apply 2–4 times per week as necessary.

Because Kushie Kush is a concentrated bloom supplement, consider the strength of your base nutrient solution and any other PK additives already being used when building your feeding program.

When Do I Use Kushie Kush?

For a standard eight-week flowering cycle:

This short application window makes Kushie Kush different from a general flowering base nutrient. It is intended as a targeted bloom booster, not as the plant's complete fertilizer program.

What Makes the 1-3-8 Formula Different?

The nutrient ratio is the interesting part of Kushie Kush.

For every 3% available phosphate, the formula contains 8% soluble potash. Potassium is heavily involved in plant water regulation, enzyme activity, carbohydrate transport and numerous physiological processes that become increasingly important as a plant supports developing flowers.

Kushie Kush therefore provides a strong flowering-stage potassium contribution without resorting to the extremely phosphorus-heavy ratios found in some conventional PK boosters.
