Cronk Nutrients – PuurOrganics Feed Chart GuidanceUpdated 2 days ago

🌿 Program Overview

The PuurOrganics Feed Program is Cronk Nutrients’ fully organic feeding system, designed for growers who want clean, natural plant nutrition without sacrificing performance.
This guide explains how to use the PuurOrganics line week-by-week — from seedling through harvest — with full mixing instructions, pH guidance, and additive use.
Whether you’re growing in living soil or a hybrid organic medium, this program ensures balanced growth, smooth transitions, and superior flavor.

Measurement Units: Milliliters (mL) per Gallon

General Mixing Instructions

  1. Always begin with clean, pH-balanced water (target 6.0–6.4 pH).

  2. If using Armadillo Armour, add it first and only once per week, then continue with the order below.

  3. Add nutrients in this order:

    1. PuurBalance

    2. PuurCalMag

    3. PuurNitro

    4. PuurPhos

    5. PuurK

    6. Sticky Bandit

    7. Monkey Juice

  4. Stir thoroughly after each addition.

  5. Allow the mix to sit for 10–15 minutes, then recheck pH before watering.

  6. Maintain water temperature between 68–72°F (20–22°C) for optimal nutrient stability and uptake.

💡 Tip: If using Armadillo Armour, mix it separately or before other nutrients to prevent precipitation and ensure even distribution.

Optional Additives

Use these to enhance your grow:

  • Armadillo Armour → Adds silica and improves plant strength.

  • Sticky Bandit → Organic resin enhancer during flowering.

  • Monkey Juice → Microbial inoculant to boost nutrient uptake and root health.

💡 These can be used throughout the cycle or added specifically during veg and flower as per the chart.


Mixing Ratios for Larger Batches

Multiply the rate (mL per gallon) by the number of gallons in your reservoir.

Example – 10 Gallons (Veg Week 3):

  • PuurNitro: 5 × 10 = 50 mL

  • PuurPhos: 3 × 10 = 30 mL

  • PuurK: 6 × 10 = 60 mL

  • PuurBalance: 1 × 10 = 10 mL

  • PuurCalMag: 4 × 10 = 40 mL

  • Monkey Juice: 4 × 10 = 40 mL (used once per week)

  • Sticky Bandit: 4 × 10 = 40 mL

  • Armadillo Armour: 0.5 × 10 = 5 mL (used once per week)


Feeding Tips

  • The PuurOrganics line performs best in organic or hybrid soil systems with microbial activity.

  • Mix only what you’ll use within 24 hours for optimal freshness.

  • Feed every watering or alternate with water in rich organic soil.

  • Observe plants and adjust feed strength ±10–20% based on response.

  • Add Armadillo Armour only once weekly to prevent silica buildup.


Optional Additives

Enhance your results with Cronk additives:

  • Armadillo Armour: Adds silica and improves plant structure (once per week).

  • Sticky Bandit: Boosts resin and terpene content.

  • Monkey Juice: Improves microbial health and nutrient uptake.

Use alongside your PuurOrganics base nutrients at standard label rates.


The PuurOrganics Feed Program provides clean, powerful nutrition for growers who want organic quality with professional-grade performance. Follow the weekly guide, adjust slightly for your setup, and your plants will reward you with vibrant growth and aromatic harvests.
