Cronk Nutrients – Autoflower Line Expert Feed Chart GuideUpdated 10 days ago
🌱 Program Overview
The Autoflower Line Expert Feed Chart is designed for advanced growers using high-intensity lighting or CO₂-enriched environments.
This schedule delivers the strongest nutrient ratios in the Cronk lineup for maximum size, resin production, and flavor quality.
Use Bonnie during the vegetative stage and Clyde for flowering. CalMag supports throughout, with Bud Booster, Sticky Bandit, Monkey Juice, and Armadillo Armour driving superior strength, aroma, and nutrient uptake.
Measurement Units: Milliliters (mL) per Gallon
Mixing Instructions
Begin with clean, pH-balanced water.
If using Armadillo Armour, always add it first. Stir well before adding other products.
During Veg, use Bonnie + CalMag.
During Flower, switch to Clyde + CalMag + Additives.
Add nutrients in this order:
Armadillo Armour (if used, use once per week)
Base Nutrient (Bonnie or Clyde)
CalMag
Bud Booster (used once or twice per week)
Sticky Bandit
Monkey Juice (used once per week)
Stir thoroughly after each addition.
Recheck and adjust pH before watering.
Maintain water temperature 68–72°F (20–22°C).
💡 Tip: Never mix Bonnie and Clyde in the same solution — switch bases between Veg and Flower.

Mixing Example – 10 Gallons
Multiply each rate ×10 to mix accurately.
Example – Veg Week 3:
Bonnie: 3.5 × 10 = 35 mL
CalMag: 4 × 10 = 40 mL
Sticky Bandit: 4 × 10 = 40 mL
Monkey Juice: 4 × 10 = 40 mL
Armadillo Armour: 0.5 × 10 = 5 mL
Example – Flower Week 2:
Clyde: 12 × 10 = 120 mL
CalMag: 5 × 10 = 50 mL
Bud Booster: 8 × 10 = 80 mL (used once or twice per week)
Sticky Bandit: 4 × 10 = 40 mL
Monkey Juice: 4 × 10 = 40 mL (used once per week)
Armadillo Armour: 1 × 10 = 10 mL (used once per week)
Feeding Tips
Ideal for high-output LED or HID setups.
Feed every watering; monitor runoff EC weekly.
Reduce Clyde slightly if leaf tips show burn.
Maintain pH within target range for best uptake.
Flush completely in the final week for a cleaner finish.
Additive Overview
Armadillo Armour: Add first. Provides silica for structural strength. (used once per week)
Bud Booster: Drives larger, denser flowers. (used once or twice per week)
Sticky Bandit: Enhances resin and terpene output.
Monkey Juice: Boosts root and microbial health. (used once per week)
pH & EC Guidelines
Veg (Bonnie): pH 5.8–6.2 | EC 1.2–1.6
Flower (Clyde): pH 6.0–6.4 | EC 1.6–2.0
Check runoff weekly to maintain medium balance.
