Advanced Nutrients: pH Perfect & Big Bud - Complete Usage Guide

1. Advanced Nutrients — Brand & Philosophy

Advanced Nutrients (AN) is a Canadian fertilizer brand known for its pH Perfect technology and a wide product line. The company states that it develops its fertilizers specifically for cannabis in its own laboratory.

The AN product system is divided into 3 tiers:

  • Hobbyist — basic package
  • Expert — more additives included
  • Grand Master — full additive suite

2. pH Perfect Technology

Proprietary technology: nutrients automatically adjust pH to the 5.5–6.3 range.

  • Chelate matrix: pH Perfect carries an extensive matrix of chelates — including zwitterionic chelates — alongside fulvic and humic acids, which is what keeps micronutrients available across a wide pH range
  • Buffering agents: maintain stable pH
  • Limitations: only works with AN base nutrients; source water with EC > 0.4 may reduce effectiveness
  • You should still measure pH periodically to verify

3. Base Nutrients: Grow – Micro – Bloom (3-part)

Part Function
Grow Nitrogen and potassium for veg
Micro Backbone, used throughout
Bloom Phosphorus and potassium for flowering
  • Dosage: follow the label or the Nutrient Calculator at advancednutrients.com
  • Rule: always mix MICRO first, then add Grow or Bloom

4. Key Additives

Product Timing
Big Bud Weeks 2–4 bloom

6. Tips & Common Mistakes

Tips

  • Use the Nutrient Calculator at advancednutrients.com
  • Start at 50% of recommended dosage
  • pH Perfect works best with RO water or EC < 0.3
  • Do not mix AN with nutrients from other brands
  • Keep solution temperature at 18–22°C for Voodoo Juice

Mistakes to Avoid

  • Using Big Bud throughout bloom → excess PK, lockout
  • Mixing Grow and Micro simultaneously → Ca precipitation
  • Using Overdrive and Big Bud in the same week → overload
  • Not flushing at the end when using AN synthetic nutrients
  • Buying counterfeit AN → no pH Perfect technology
