Advanced Nutrients Kushie Kush 1 Litre - Kush-Specific Bloom Booster
Best for: Growers running Kush-lineage strains who want a booster dialled specifically to that genetic profile rather than a generic PK feed.
Our thoughts
This is a genuinely unusual product - Advanced Nutrients built it specifically for Kush-type genetics rather than as a general-purpose booster, and as far as we can find, nobody else makes a strain-family-specific bloom additive quite like this. Whether that specificity is worth it over a good general PK booster depends on how confident you are in your strain's genetics.
Kushie Kush is a bloom booster from Advanced Nutrients formulated specifically for Kush-lineage cannabis genetics, rather than as a general-purpose PK additive for any strain. The formula combines extra phosphorus, potassium and a measured amount of nitrogen, alongside a broad spectrum of amino acids intended to support protein building and metabolism during flowering. Advanced Nutrients markets it as inducing more profuse flowering and stronger aromatic oil production specifically in Kush-type plants.
It's a niche product by design - Advanced Nutrients themselves describe it as the only strain-specific bloom booster of its kind on the market, built after research into what Kush genetics respond to versus other cannabis lineages.
How it compares
Kushie Kush doesn't have a direct like-for-like competitor because of its strain-specific positioning, so it's best compared against general bloom boosters.
- Vs generic PK boosters like House & Garden Bud-XL or Canna PK 13/14: those work across any strain but aren't tuned to Kush genetics specifically; Kushie Kush trades that broad applicability for a narrower, targeted formula.
- Vs Advanced Nutrients' own general boosters (Bud Candy, HammerHead): those complement any base feed regardless of genetics; Kushie Kush is designed to be added specifically when growing Kush-lineage plants.
- Vs running no dedicated strain booster at all: growers of Kush genetics who currently just run a base nutrient and a general PK booster are the target audience for this add-on.
It's a specialist product for a specific genetic category rather than a universal bloom additive.
Usage guidance
Kushie Kush is used during a specific flowering window rather than through the whole cycle.
Dosage
Use at 2ml per litre of nutrient solution, typically from around week 2 through to week 5 or 6 of the flowering phase depending on your strain's flowering length.
Mixing
Add to your reservoir alongside your base nutrient and other bloom-phase additives, mixing thoroughly.
Strain match
This is formulated for Kush-lineage genetics specifically - if you're growing a different genetic family, a general PK booster is likely to be the more appropriate choice.

Who this is for
- Growers running Kush or Kush-hybrid genetics who want a strain-matched booster
- Advanced Nutrients users building a full bloom-phase feeding programme around their genetics
- Growers curious about strain-specific additives who want to test one against a general PK booster
Not necessary for non-Kush genetics - save the spend for a general-purpose booster if that's what you're growing.
Our take
It's a genuinely unusual product in a market full of one-size-fits-all boosters, and the specificity is the whole appeal. If you're growing Kush genetics and want to squeeze out everything that lineage has to offer, this is built with exactly that in mind.
One we sell a lot of to growers who already know their genetics and want a booster matched to them rather than a generic option.
