Feeding & Mixing FAQWhen should I start feeding my plants Cronk Nutrients?
Begin feeding 1–2 weeks after germination when true leaves appear. Cronk feed charts are designed for cannabis, so full strength is safe—reduce only if desired.
Feeding & Mixing FAQCan I mix all Cronk Nutrients together?
Yes, but add nutrients one at a time to water—never mix concentrates directly—to prevent lockout and ensure even nutrient absorption.
Feeding & Mixing FAQHow often should I feed my plants Cronk Nutrients?
Feed every other watering in soil or coco, and daily in hydro. Adjust frequency based on leaf color, growth rate, and runoff readings.
Feeding & Mixing FAQDo I need to use CalMag with Cronk Nutrients?
Use CalMag with Bonnie & Clyde, and supplement weekly with 3-Part or PuurOrganics for extra calcium and magnesium support, especially in coco or RO setups.
Feeding & Mixing FAQWhich Cronk Nutrient system should I use for my grow?
Use Bonnie & Clyde for autoflowers, the 3-Part Base for photoperiods, and PuurOrganics for fully organic growing setups.
Feeding & Mixing FAQCan I use Cronk Nutrients with other brands?
Yes, but start with Cronk Nutrients alone to gauge results and avoid overloading plants with excess salts or overlapping nutrients.
Feeding & Mixing FAQCan I use Cronk Nutrients in DWC or hydroponics?
Yes, the 3-Part Base and CalMag perform well in hydro systems. Avoid PuurOrganics to prevent clogging from organic matter.
Feeding & Mixing FAQCan I use Sticky Bandit and CalMag with PuurOrganics?
Sticky Bandit works with PuurOrganics no problem. CalMag works too, but here's the better organic path most growers should take instead.
Feeding & Mixing FAQIs there anything else I should buy to help my plants thrive?
Boost your grow with Sticky Bandit for flavor, Monkey Juice for microbes, Bud Booster for density, and Armadillo Armour for stem strength.
Feeding & Mixing FAQHow can I prevent nutrient lockout when feeding my plants?
Prevent nutrient lockout by pH balancing after mixing, flushing every 2–3 weeks, and maintaining microbial balance with Monkey Juice.
Feeding & Mixing FAQCan I use Cronk Nutrients in a drip irrigation or auto-watering system?
Cronk mineral nutrients are drip-safe; avoid PuurOrganics in auto-watering systems to prevent clogs. Flush lines weekly and stir reservoirs often.
Feeding & Mixing FAQCan I foliar feed with Cronk Nutrients?
Foliar feed with diluted Cronk nutrients like CalMag or PuurBalance during low light; avoid spraying in flower to prevent mold.
Feeding & Mixing FAQHow do I transition from vegetative to flowering nutrients?
Begin bloom feeding when pistils appear; lower nitrogen and increase phosphorus and potassium using Cronk’s feeding chart.
Feeding & Mixing FAQShould I use plain water between feedings?
Alternate nutrient and plain water feedings to prevent salt buildup; monitor EC runoff for balanced feeding.
Feeding & Mixing FAQWhy are pH and EC important in plant growth?
pH determines nutrient availability, and EC measures nutrient strength. Together they control how efficiently plants feed. Keeping both in range ensures healthy roots, balanced uptake, and maximum yield.
Troubleshooting & DeficienciesWhy are my plant leaves turning yellow?
Yellow leaves often mean nitrogen deficiency, pH imbalance, or salt buildup. Flush and feed with CalMag to restore green growth.
Troubleshooting & DeficienciesWhy are my leaves curling up or down?
Leaf curl often signals heat, overwatering, or excess nutrients. Reduce feed and improve airflow to restore balance.
Troubleshooting & DeficienciesMy plants have brown spots on the leaves—what’s happening?
Brown spots mean calcium or magnesium deficiency; add CalMag and correct pH to restore leaf health.
Troubleshooting & DeficienciesWhy is my plant’s growth uneven or stunted?
Uneven growth is caused by lighting or nutrient imbalance—rotate plants and use Monkey Juice to boost root health.
Troubleshooting & DeficienciesWhy are my buds small and airy?
Small, airy buds in late flower usually trace back to one of seven causes: light intensity, phosphorus and potassium supply, excess nitrogen, heat, root problems, harvesting too early, or genetics. Here's how to diagnose and fix each one.
Troubleshooting & DeficienciesMy plants look pale even though I’m feeding—what’s wrong?
Pale leaves mean poor nutrient uptake; adjust pH, flush, and use Monkey Juice to restore root absorption.
Troubleshooting & DeficienciesWhy are my plants drooping after watering?
Drooping plants often mean overwatering or poor drainage. Let soil dry slightly between waterings and ensure aeration.
Troubleshooting & DeficienciesMy pH keeps fluctuating — how do I fix it?
pH swings often result from salt buildup, unstable water, or poor calibration. Flush, recalibrate, and maintain stable temperatures for consistent pH.
Troubleshooting & DeficienciesWhy are my stems purple or red?
Purple stems can mean genetics, cold stress, or phosphorus lockout from pH imbalance. Keep temps warm and pH in range to fix it.
