NPK FORMULA EXPLAINED

2-6-8: Optimized for Flowering Stage

Our bloom formula is specifically engineered for the flowering phase when plants need maximum phosphorus and potassium with minimal nitrogen.

N - 2%

Nitrogen
Low nitrogen prevents excessive foliage during bloom, directing energy toward flower and fruit production.

P - 6%

Phosphorus
High phosphorus drives ATP energy transfer, bud initiation, flower density, and essential oil production.

K - 8%

Potassium
Elevated potassium enhances flower quality, color, aroma, and overall harvest weight.

⚠️ Critical Mixing Order (NEVER mix concentrates directly)

  1. Cal-Mag Plus — add to water and dissolve fully
  2. Micro Green — stir to clarity
  3. Grow Green — for veg/transition
  4. Blossom Green — for flowering
  5. Adjust pH last — target 5.8–6.5 during bloom

FREQUENTLY ASKED QUESTIONS
Q When should I switch from Grow Green to Blossom Green?

Switch at flower initiation (e.g., 12/12 light cycle for photoperiod crops). During the transition period (weeks 7–8), use equal parts Grow Green and Blossom Green (10 ml/gal each). Then taper Grow Green to 0 and increase Blossom Green to 20 ml/gal at peak bloom.

Q Why is phosphorus emphasized in bloom formulas?

Phosphorus is critical for energy transfer (ATP) and flower formation. Elevated P during bloom supports bud initiation, flower density, maturity timing, and essential oil production for quality harvests.

Q Do I have to use Cal-Mag Plus?

Yes — always add Cal-Mag Plus first to prevent Ca/Mg precipitation and keep nutrients available throughout the grow cycle. This is especially important with RO water and coco coir media.

Q What EC and pH should I target?

Target EC rises from 0.5–0.8 (seedlings) to approximately 2.0–2.5 (peak bloom). Maintain pH 5.5–6.5 throughout, with 5.8–6.5 during bloom being optimal for phosphorus availability.

Q Can I use Blossom Green during vegetative stage?

Yes, at low rates alongside Grow Green. See the feeding schedule for 1.25–5 ml/gal recommendations during vegetative stages. The full 20 ml/gal rate is reserved for peak bloom.

Q How do I store the powder?

Our fertilizer is hygroscopic (absorbs moisture from air). To prevent clumping:

  1. Keep the bag sealed tight between uses
  2. Store in a cool, dry place out of direct sunlight
  3. If it clumps, simply break it up — efficacy is not affected
