Bonnie & Clyde Feed Schedule
Complete 2-Part Autoflower System
This kit includes two specialized nutrients designed specifically for autoflowers:
- Bonnie (6-5-4) - Vegetative growth nutrient for weeks 2-4
- Clyde (3-6-5) - Flowering nutrient for weeks 5-10
⚠️ Strongly Recommended to Add:
- CalMag (2-0-0) - Essential calcium and magnesium supplement. Autoflowers are heavy CalMag feeders, and this supplement prevents common deficiencies throughout the entire grow cycle.
Important: Never mix Bonnie and Clyde together. Use Bonnie during vegetative stage, then switch to Clyde for flowering.

Mixing Instructions
1
Start with Clean Water
Use room temperature water (18-22°C / 65-72°F) in a clean container.
2
Add Base Nutrient First
During veg (weeks 2-4), add Bonnie and stir thoroughly. During flower (weeks 5-10), add Clyde and stir thoroughly. Never use both together.
3
Add CalMag Second
After base nutrient is mixed, add CalMag and stir thoroughly. If using RO water, you may add CalMag first.
4
Check pH & EC
Target pH: 5.8-6.3 (hydro/coco) or 6.2-6.5 (soil). Target EC: See chart above for weekly ranges.
5
Apply to Plants
Water until 10-20% runoff in drain-to-waste systems. Feed 1-2 times per week depending on plant needs.
Bonnie & Clyde Pro Tips
- Transition timing: Switch from Bonnie to Clyde when you first see pre-flowers (usually around week 4-5)
- CalMag is essential: Autoflowers are heavy CalMag feeders - don't skip this supplement
- Coco growers: Feed with every watering at lower strength rather than higher strength less frequently
- Final flush: Flush with plain pH'd water during the last week for better taste and quality
- Storage: Store bottles in a cool, dark place and shake well before each use

Frequently Asked Questions
Find answers to common questions
What makes the Bonnie & Clyde Autoflower Line different from other nutrients?
Bonnie & Clyde are precision-formulated nutrients for autoflowers, giving balanced nutrition for both fast growth (Bonnie) and strong flower production (Clyde). They're clean, easy to use, and designed for the full autoflower lifecycle.
Can I use Bonnie & Clyde on photoperiod plants too?
Yes. While optimized for autoflowers, Bonnie & Clyde can be used on photoperiod plants with minor feed adjustments. They deliver consistent results across soil, coco, and hydro systems.
How often should I feed my autoflowers with Bonnie & Clyde?
Feed every watering or every other watering depending on your medium. Autoflowers prefer light, consistent feedingsrather than heavy doses. Always follow the Cronk Nutrients feeding chart for best results.
Do I need supplements with Bonnie & Clyde?
For best results, use CalMag with Bonnie during vegetative growth and with Clyde during flowering. This supports strong structure and bud development. Optional boosters like Sweetness or Silica Boost enhance flavor and plant strength.
Are Bonnie & Clyde organic or synthetic?
They're synthetic mineral nutrients built for fast uptake and precision feeding, perfect for the short life cycle of autoflowers. For an organic option, see our PuurOrganics Line.
When do I switch from Bonnie to Clyde?
Switch to Clyde (bloom) when your plants show pre-flowers, typically around week 3–5. Bonnie drives early root and leaf growth; Clyde fuels buds and resin production.
Can I use Bonnie & Clyde in soil, coco, or hydroponics?
Yes. The Bonnie & Clyde Line works in soil, coco, and hydro, delivering consistent results with proper pH and EC management.
What is the shelf life of Bonnie & Clyde nutrients?
Bonnie & Clyde have a 3–5 year shelf life when stored in a cool, dark place with lids tightly sealed. As synthetic fertilizers, they stay stable and effective long-term. Avoid freezing or high heat for best preservation.
