Product Overview
Clyde 3-6-5 is a complete flowering nutrient formulated specifically for autoflowering plants during their rapid 5-7 week bloom phase. The phosphorus-forward formula drives flower initiation and energy-intensive development while reduced nitrogen prevents vegetative interference during reproduction.
Autoflowers complete flowering faster than photoperiod plants, demanding immediate nutrient availability without gradual transition periods. Clyde delivers optimized bloom nutrition from the moment pre-flowers appear, with elevated phosphorus for ATP energy production and potassium for flower density, terpene synthesis, and resin development.
Key Benefits
- Elevated phosphorus (6%) powers energy-intensive flower development and maturation
- Increased potassium (5%) enhances flower density, stem strength, and terpene production
- Reduced nitrogen (3%) prevents leafy growth that diverts resources from flowers
- Chelated micronutrients including boron, molybdenum, and zinc for reproductive health
Ideal For
Autoflower growers transitioning from vegetative growth. Switch completely from Bonnie to Clyde when pre-flowers appear. Never mix Bonnie and Clyde together—they are designed for distinct growth stages.

Frequently Asked Questions
What is Clyde and what does it do?
A bloom-stage base for autos with a 3-6-5 NPK and chelated micros to drive flower set, bud density, and overall bloom quality.
When do I switch to Clyde?
Start when autos show pistils and run it through harvest (roughly Weeks 4–10 on typical schedules).
Do I use Clyde with CalMag?
Yes—always pair Clyde with CalMag during bloom for complete nutrition.
Should Bonnie and Clyde ever be used together?
No—Bonnie is veg, Clyde is bloom, and they’re never used at the same time.
Which additives pair best in bloom?
Bud Booster for extra PK and density; Sticky Bandit can run throughout; Monkey Juice after pH to protect microbes.
What grow media and setups does Clyde work in?
Safe and effective in soil, coco, and hydro/DWC, indoors or outdoors—just manage EC and pH
Can I use Clyde on non-auto plants like vegetables or ornamentals?
Yes—while formulated for autos, the line is also suitable for other plant types when used correctly and per the feed chart.
Are Cronk Nutrients easy to use for beginners?
Yes—our nutrients are simple, stable, and forgiving. Each bottle lists clear mixing directions, and our feed charts make it easy to get started.
