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

1. Advanced Nutrients — Brand & Philosophy

Advanced Nutrients (AN) is a Canadian fertilizer brand renowned for its pH Perfect technology and diverse product line. AN takes pride in being the only company that researches fertilizers specifically designed for cannabis, with its own dedicated 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.

Multi-level chelation: 5 types of chelates (EDDHA, DTPA, EDTA) keep micronutrients dissolved 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	NPK	Function
Grow	1-0-4	Nitrogen and potassium for veg
Micro	2-0-0 + micronutrients	Backbone, used throughout
Bloom	0-1-2	Phosphorus and potassium for flowering

Dosage: each part 1–4 ml/L
Rule: always mix MICRO first, then add Grow or Bloom

4. Key Additives

Product	NPK	Dosage	Timing
Big Bud	0-1-3	2 ml/L	Weeks 2–4 bloom
Voodoo Juice	4 bacterial strains	2 ml/L	First 2 weeks veg + bloom
B-52	Vitamin B complex + humic acid	2 ml/L	Throughout
Overdrive	Late booster	2 ml/L	Weeks 5–6 bloom
Flawless Finish	Flushing solution	2 ml/L	Final week

5. Feeding Schedule (Hobbyist)

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
