Always add Armadillo Armour first, then CalMag. For the 3-Part Base, mix Micro, then Grow, then Bloom. For Bonnie & Clyde, mix Bonnie or Clyde first depending on stage, then adjust pH.

What order should I mix Cronk Nutrients in?

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.

Start feeding once your seedlings have developed their first set of true leaves &#x2014; typically 7&#x2013;14 days after germination.Cronk Nutrients feed charts are specifically formulated for cannabis, so you can follow them as-is without heavy dilution.If you&#x2019;re growing sensitive strains or in very light soil, you may start at half strength for the first feeding, then transition to the full schedule as your plants establish. Always monitor leaf color and growth rate to fine-tune your feeding intensity.Pro Tip: Our feed charts are tested for optimal EC and nutrient balance &#x2014; following them closely ensures consistent results from seed to harvest.<script type="application/ld+json">

When should I start feeding my plants Cronk Nutrients?

Yes, but add nutrients one at a time to water—never mix concentrates directly—to prevent lockout and ensure even nutrient absorption.

Yes &#x2014; but never mix nutrients in their concentrated form. Always add them one at a time to water, following the correct order. Mixing directly together can cause nutrient lockout or precipitation.<script type="application/ld+json">

Can I mix all Cronk Nutrients together?

Feed every other watering in soil or coco, and daily in hydro. Adjust frequency based on leaf color, growth rate, and runoff readings.

Feed on an alternating schedule: Feed &#x2192; Water &#x2192; Feed for soil or coco. In hydro systems, feed daily or maintain your reservoir consistently. Watch leaf color, growth rate, and runoff EC/PPM to fine-tune frequency.<script type="application/ld+json">

How often should I feed my plants 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.

It depends on which Cronk Nutrient line you&#x2019;re using.<ul style=" text-decoration: none;"><li>Bonnie &amp; Clyde (Autoflower Line):Yes &#x2014; we recommend using CalMag (2-0-0) alongside Bonnie during the vegetative stage and Clyde during the flowering stage. Autoflowers are fast-growing and tend to show calcium and magnesium deficiencies quickly, especially in coco coir or under LED lighting.</li><li>3-Part Base (Micro, Grow, Bloom):CalMag is not required, as the formula already includes balanced calcium and magnesium levels. However, supplementing once per week can help prevent minor deficiencies in high-demand environments or when using RO (reverse osmosis) water.</li><li>PuurOrganics (Organic Line):CalMag is also not required, but an occasional light supplement can help maintain consistent Ca/Mg availability, particularly in soft water or coco-based mediums.</li></ul>Pro Tip: Always mix CalMag early in your nutrient solution (after Armadillo Armour if using it) and allow it to sit for 5&#x2013;10 minutes before adding your base nutrients.<script type="application/ld+json">

Always mix CalMag early, after Armadillo Armour, and let it sit 5–10 minutes before adding base nutrients."
 }
 }
 ]
}
</script>

Do I need to use CalMag with Cronk Nutrients?

Use Bonnie & Clyde for autoflowers, the 3-Part Base for photoperiods, and PuurOrganics for fully organic growing setups.

<ul style=" text-decoration: none;"><li>Autoflowers: Use Bonnie &amp; Clyde (6-5-4 / 3-6-5) for simplicity and fast cycles.</li><li>Photoperiods: Use the 3-Part Base (Micro, Grow, Bloom) for precise control.</li><li>Organic growers: Choose&#xA0;PuurOrganics, our 5-part liquid organic fertilizer line.</li></ul> <script type="application/ld+json">

Which Cronk Nutrient system should I use for my grow?

Yes, but start with Cronk Nutrients alone to gauge results and avoid overloading plants with excess salts or overlapping nutrients.

You can mix Cronk Nutrients with other products, but we recommend starting with Cronk alone to gauge your plant&#x2019;s response. Avoid overlapping additives that may double up on NPK or salts. If you want to confirm before mixing reach out to us at <a href="mailto:help@cronknutrients.com">help@cronknutrients.com</a>&#xA0;with what nutrients you would like to use with our products and we can give you a more in-depth guide.&#xA0;

Can I use Cronk Nutrients with other brands?

Yes, the 3-Part Base and CalMag perform well in hydro systems. Avoid PuurOrganics to prevent clogging from organic matter.

Yes &#x2014; the&#xA0;3-Part Base and&#xA0;CalMag work perfectly in DWC and hydro systems. Avoid using&#xA0;PuurOrganics, as its organic material may clog lines or pumps.

Can I use Cronk Nutrients in DWC or hydroponics?

Yes, combine Sticky Bandit and CalMag with PuurOrganics for stronger growth, improved energy, and balanced calcium and magnesium levels.

Yes &#x2014; both can be safely combined with&#xA0;PuurOrganics to enhance nutrient uptake and plant health. Sticky Bandit provides carbohydrates for energy, and CalMag supports strong structure and chlorophyll production.

Can I use Sticky Bandit and CalMag with PuurOrganics?

Boost your grow with Sticky Bandit for flavor, Monkey Juice for microbes, Bud Booster for density, and Armadillo Armour for stem strength.

For best results, pair your base nutrients with these Cronk additives:<ul style=" text-decoration: none;"><li>Sticky Bandit: Carbohydrates for flavor and resin.</li><li>Monkey Juice: Beneficial microbes for nutrient absorption.</li><li>Bud Booster: Extra PK for dense flowers.</li><li>Armadillo Armour: Silica for stronger stems.</li></ul>

Is there anything else I should buy to help my plants thrive?

Prevent nutrient lockout by pH balancing after mixing, flushing every 2–3 weeks, and maintaining microbial balance with Monkey Juice.

Nutrient lockout happens when pH levels drift outside the ideal range or salts build up in your medium. Always pH your water after adding nutrients, maintain consistent EC levels, and flush your medium with clean, pH-balanced water every 2&#x2013;3 weeks. Using Monkey Juice helps maintain microbial balance and improve nutrient uptake.

How can I prevent nutrient lockout when feeding my plants?

Cronk mineral nutrients are drip-safe; avoid PuurOrganics in auto-watering systems to prevent clogs. Flush lines weekly and stir reservoirs often.

Yes. Cronk Nutrients&#x2019; mineral-based formulas (Classic Line and Bonnie &amp; Clyde) work great in drip systems. However, we do&#xA0;not recommend using PuurOrganics in auto-watering or Autopot systems, as organic matter may cause clogs. Always flush lines weekly and agitate your reservoir before each feed.

Can I use Cronk Nutrients in a drip irrigation or auto-watering system?

Foliar feed with diluted Cronk nutrients like CalMag or PuurBalance during low light; avoid spraying in flower to prevent mold.

Yes, foliar feeding can boost growth and correct deficiencies quickly. Use a diluted solution (&#xBC; strength) and mist leaves during low-light hours. CalMag or PuurBalance work especially well as foliar sprays. Avoid foliar feeding during flowering to prevent mold.

Can I foliar feed with Cronk Nutrients?

Begin bloom feeding when pistils appear; lower nitrogen and increase phosphorus and potassium using Cronk’s feeding chart.

When plants show the first signs of flowering (white pistils), transition by tapering off nitrogen and increasing phosphorus and potassium. With Cronk Nutrients, reduce Grow as done in the feed chart or switch to Clyde if growing autoflowers according to the feeding chart.

How do I transition from vegetative to flowering nutrients?

Alternate nutrient and plain water feedings to prevent salt buildup; monitor EC runoff for balanced feeding.

Yes. Alternate nutrient feeding with plain, pH-balanced water to prevent salt buildup. In soil, feed&#x2013;water&#x2013;feed. In coco, feed more frequently with lighter nutrient strength. Always monitor runoff EC for buildup signs.

Should I use plain water between feedings?

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.
