Choosing the Right Cronk Nutrients for Your GrowUpdated 3 days ago

When starting your grow, one of the biggest questions is which nutrients to use.

At Cronk Nutrients, we’ve made it easy for growers of all experience levels to pick the perfect formula — whether you’re growing cannabis, houseplants, or garden vegetables.

Each Cronk line is built for a specific growing style, giving you the flexibility to choose what fits your goals, your medium, and your level of experience.

The Cronk Classic Line (3-Part System)

Best for: Growers who want full control and flexibility

Works great in: Soil, coco, hydroponics, and drain-to-waste systems

The Classic 3-Part Base System — Grow (2-1-6), Micro (5-0-1), and Bloom (0-5-3) — gives you the power to fine-tune nutrients for every growth stage.

Why growers love it:

✅ Complete control over NPK ratios at every stage

✅ Clean, liquid formula that mixes easily — no residue or clumping

✅ Suitable for all plant types and all grow systems

✅ Perfect for both beginners and advanced growers

How to use it:

• During the vegetative stage, focus on Grow + Micro for lush green growth.

• In bloom, shift to Bloom + Micro to boost flowering and yield.

• Always mix Micro first, then Grow and Bloom, checking pH (5.8–6.2 for coco/hydro; 6.0–6.8 for soil).

The Classic Line is the go-to option for anyone who wants a pro-level feeding system that’s easy to adjust as your plants grow.

Bonnie & Clyde (Autoflower Nutrients)

Best for: Autoflower growers who want simplicity and results

Works great in: Soil, coco, and soilless mixes

Autoflowers grow fast and don’t wait for you to switch their light cycle — that’s why they need a nutrient system designed for their shorter life span.

Bonnie & Clyde are perfectly balanced to give autos everything they need, without the risk of overfeeding.

• Bonnie (6-5-4): Fuels strong vegetative growth and healthy roots

• Clyde (3-6-5): Powers dense flowers, resin production, and terpene quality

Why growers love it:

✅ Two bottles — simple and streamlined

✅ Perfectly balanced for 8-12-week autoflower cycles

✅ Delivers complete nutrition without heavy salts

✅ Less guesswork — more time enjoying the grow

Pro tip:

Add CalMag (2-0-0) alongside Bonnie during veg and Clyde during flower.

This keeps calcium and magnesium levels steady, especially under LED lights or in coco coir.

Bonnie & Clyde are ideal for new growers, small spaces, and anyone who wants a simple, efficient nutrient plan that still delivers professional results.

PuurOrganics (Organic Line)

Best for: Growers seeking clean, plant-based, organic nutrition

Works great in: Soil, living soil, coco, and peat-based mixes

If you prefer to grow the natural way, PuurOrganics delivers high-performance results with zero synthetic salts.

Made from upcycled, eco-friendly plant materials, this line offers complete nutrition that’s easy to use and completely water-soluble.

Why growers love it:

✅ 100% plant-based & eco-friendly

✅ No mess — liquid, water-soluble, and sediment-free

✅ Ideal for living soil and regenerative gardens

✅ Gentle on microbes, strong on results

Important tip:

PuurOrganics is not recommended for AutoPot systems or DWC hydro setups — organic matter can clog lines.

Stick with soil, coco, or drip-to-waste systems for best performance.

PuurOrganics makes organic growing simple — clean, efficient, and powerful enough for any crop.
