BlueGold® Maxi-CAL™ (21% Calcium)


Maxi-CAL™ is for use in VEG cycles only, as it is SO powerful it will push out K levels in FLWR cycles.

Use BlueGold® Maxi-CAL™ with our complete Nutrient Lineup or to enhance your non-synthetic inputs. With BlueGold® Maxi-CAL™ you can expect to see huge fruit and flower sets, optimized plant immune system, and set up for a high BRIX cycle.

BlueGold® Maxi-CAL™ is 100% Natural and NOP Compliant for Certified Organic Programs (please contact your certifier before use). BlueGold® Maxi-CAL™ is deliverable instant Calcium. It’s set apart from other Calcium sources because it contains a unique negative charged source of CaC03, which results in explosively quick Calcium uptake. Its unique blend of Calcium sources is from NOP Compliant Raw Oceanic Deposits, Plant Saponins, and Carbohydrates that are Trade-Secret Manufactured without high heat, acids, solvents, or harsh chemicals to reveal higher available levels of CaC03 and preserve inherent all natural biological strains. By dry weight analysis, Maxi-CAL™ contains over 21% available CaC03 and works extremely quick in the VEG cycle (*when using BlueGold® Nutrient Systems and proper pH is established) of any plant and strain with immediate plant sap results. Maxi-CAL™ is for use in VEG cycles only, as it is SO powerful it will push out K levels in FLWR cycles. The industry has Cal-Mag problems due to improper pH feeding and improper Ca/Mg/P loading in VEG cycles. Calcium is the second most important nutrient in your entire Nutrient lineup. No nutrient processes without sufficient Phosphate – and sufficient Phosphate will not process unless there is sufficient Calcium. Phosphate is known as the King of Minerals, and Calcium is known as the Queen of Minerals. You want to jam Calcium in VEG. If you push it in FLWR, you simultaneously push out Potassium. Without properly balanced Potassium, you experience tip burn, small buds, small fruit, etc. High Potassium will also push out Calcium. Similarly, too much Phosphate will push out Calcium in VEG. By establishing the plants in the VEG cycle with huge amounts of available Ca, like Maxi-CAL™, you set the plant up to carry over the Calcium into the FLWR cycle for huge fruit and flower sets, reproduction, optimized plant immune system, and high BRIX levels. Proper nutrient ratios via Root Zone & Foliar feeds will always dictate deliverable balanced nutrients in the plant sap is the key to massive production and the ability to govern susceptibility to pest and disease. Balanced nutrition is water-soluble deliverable nutrition. Apply in most grow media (caution do not use synthetically enhanced or high Na/Ch media with BlueGold®). By itself, Maxi-CAL™ will not harm ANY plant, floral, strain, biology, system, human, animal, environment, or beneficial (bird, bee, butterfly, earthworm, etc.). Supercharge your grows by optimizing nutrition. BlueGold® Maxi-CAL™ can be used to enhance your current inputs, but it is primarily meant to be used with our nutrient lineup. For ALL plants we recommend BlueGold® Hydro protect them from frost, freeze, and heat. BlueGold® Maxi-CAL™ is 100% American made.

As the manufacturer we offer Guaranteed Results when used as directed. A limited guarantee restricted to exclusive use with BlueGold® products and systems subject to soil, plant, water conditions, and Postal damages. No warranty.

By itself, BlueGold® Maxi-CAL™ will never cause burning when used at the recommended rates. Do NOT combine with pesticides/chemicals/plant cleaners/etc. BlueGold® Maxi-CAL™ magnifies anything it touches and greatly enhances nutrient uptake. All BlueGold® Solutions have the ability to magnify anything they are mixed with or come into contact within the soil, water, or on plant leaf surfaces. Very recent (months prior) or current use of chemicals like fertilizers, herbicides, fungicides, algaecides, bactericides, miticides, pesticides, biocides, fumigants, plant growth regulators, pH Up/Down chemicals, dyes, etc., – all can cause an unfavorable interaction due to the BlueGold® Solution magnifying the strength of said chemical. Strengthened doses of those chemicals can result in direct stress, burning, or death of plants. BlueGold® Solutions by themselves, without chemical interactions, will never cause these issues in any plant or soil (when used as directed)Users must respect BlueGold® labels and reduce NPK/synthetic inputs by +/- 90%. If by user choice, against our directions/recommendations, to use chemical inputs by combining with BlueGold®, they must be reduced by 90% or more. If you quickly move the pH to 6.4 with the help of pH adjusters, without adjusting inputs, you’re drastically making inputs more available, which results in stressed, burned, or dead plants from too big of a hit from the nutrients that are now available at a much higher % than previously. Especially when all the excess stored up chemicals inputs, flood into the plants at even higher EC/PPM values. Likewise, if you do not adjust inputs while using BlueGold®, as soil/sap pH is driven to 6.4, the same can happen over an extended period depending on soil and watering conditions. We do not advocate mixing BlueGold® with any chemicals. This all only applies to chemical-based products and does not apply to organic-based products except for humic and fulvic acids as they are already in the BlueGold®. Best used with non-city or chemically treated water sources. Best if RO, distilled, or rain/spring water is used. BlueGold® works and works very well in all organic situations with no side effects. If you encounter problems in the plants from the chemicals by your choice, then STOP.


Calcium should be applied according to plant sap analysis. Depending on strains and sap test, use the below rates (per 1 gallon) for weekly applications of Maxi-CAL™. For fastest uptake, fertigate then foliar. Due to natural plant saponins, always add Maxi-CAL™ to water to reduce minimal foaming. Shake extremely well before use but please open slowly. There is approximately 7+ lbs of Calcium 1 gallon at. <1 micron.

    • VEGETATIVE – Maxi-CAL™ is for use in VEG cycles only, as it is SO powerful it will push out K levels in FLWR cycles.
      • Zone: 8 – 10 mL per gallon of clean water
      • Foliar: 10 -18 mL per gallon of clean water

Plants may require varying watering cycles due to light, humidity, temp. Water as needed – keep soil moisture rate at 27% do not exceed 33% zone. Keep soil/sap pH at 6.3 in FLOWER for best flower/blooms results.

  • Sometimes there can be slight leaks if the carrier is extra rough with the shipping. If there is a problem with the shipment, please contact us at 1-877-732-5360 or email
  • If you have a big problem with Nutrient Lock-Out due to pH & imbalanced soil/plant sap ratios — or if you’ve recently applied chemical fertilizer or been abundantly applying NPK fertilizers with little to no results, we recommend using BlueGold® Maxi-CAL™ at 90% less the normal rate and work up to the recommended rates above.
  • BlueGold® Solutions gradually move the soil/plant sap pH towards 6.4. At this level of pH, all soil-stored and new nutrients become the most available into the plants. Successful gardening begins and ends with soil/plant sap pH at 6.4. pH below 6.4 will lock-out (9% per each 1/10th pH tick movement): Ca, Mg, K, and available Na Salts. pH above 6.4 will lock-out (9% per each 1/10th pH tick movement): P, S, Si, and all Micronutrients.

  • The leftover mix is good for 30 days. Store in cool dark place.
  • BlueGold® Maxi-CAL causes extreme root growth, caution with plastic/cloth pots (root bounding increases stress).
  • BlueGold® Maxi-CAL™ can be used with pump-up sprayers, hose-end sprayers (put on 3oz setting), and/or watering pails.
  • Safe to apply in all weather conditions, hot or cold, and before, during, and/or after rain. BlueGold® Maxi-CAL™ has been tested from 15°F to 125°F with no detriment to plants, soil, blooms. The best time to spray is early morning when dew is present.
  • BlueGold® Maxi-CAL™ is not harmful to the skin. If contact occurs, wash afterward to avoid dry skin.
