🌸 6% Phosphorus

High P formula specifically calibrated for heavy-flowering hydroponic crops

💪 8% Potassium

Enhances flower quality, color, flavor, and overall harvest weight

🌟 4-Part System

Works synergistically with Cal-Mag, Grow Green, and Micro Green

⚠️ Mixing & Compatibility

  • Start with RO/filtered water. Add Cal‑Mag first, then Micro, then Grow/Blossom.
  • Never mix concentrates directly together — dilute each in water before combining.
  • Circulate 15 minutes before measuring EC/pH; adjust pH last (5.8–6.5 during bloom).
  • Do not combine with other manufacturers' nutrients to avoid precipitation or lockout.

FREQUENTLY ASKED QUESTIONS
When should I switch from Grow Green to Blossom Green?
Flip to bloom when you change your light cycle to induce flowering. During transition (weeks 7–8), run equal parts Grow & Blossom (10 ml/gal each). Then taper Grow to 0 and raise Blossom to 20 ml/gal at peak bloom.
Why is phosphorus emphasized?
P is key for energy transfer and flower formation. Elevated P during bloom supports bud initiation, density, maturity, and essential oil production for quality harvests.
Do I have to use Cal‑Mag?
Yes — adding Cal‑Mag first prevents Ca/Mg precipitation and keeps nutrients available throughout the run.
What pH should I target?
Run 5.5–6.5 throughout; 5.8–6.5 during bloom for optimal phosphorus availability. Adjust after all nutrients are added and the solution has circulated.
