Description

Rock-solid, frosty flowers through the finish

Atami Rokzbastic is a PK 10-20 finishing bloom additive that pairs minerals with biostimulants to harden and bulk flowers in the back half of bloom. With potassium set at double the phosphorus, it targets the extra mineral demand plants have during fruiting and ripening - so flowers that finish light or airy fill out denser and firmer, without pushing your base feed to lockout levels.

Key Benefits

  • PK 10-20 ratio - phosphorus and potassium in a 1:2 balance for late-bloom bulking and hardening
  • Minerals plus biostimulants - supports flower mass without relying on synthetic hormones
  • Contains 1% iron and essential elements, low in ballast salts like sodium and chloride
  • Works with your base feed - added to the reservoir alongside your existing programme
  • Suits hydro, coco and soil, and pairs well after Bloombastic for amplified results

Flowers finishing light and underfilled?

When bloom stalls late and flowers stay airy, plants are often short of the potassium and phosphorus needed for rapid flower bulking. Rokzbastic tops that up in the reservoir without lifting overall nutrient strength too far, so you build density and firmness while avoiding the nutrient lockout that comes from simply feeding more base.

How to Use

  • All media (hydro, coco, soil): 0.5-1ml per litre of nutrient solution, alongside your base feed
  • When: the final 4-6 weeks of flowering, through fruiting and ripening
  • It raises solution EC - monitor and adjust, especially when stacking with other high-PK products
  • Introduce gradually if new to it and watch plant response before increasing the rate
