Commercial Edition® nutrients and additives are only available exclusively from Dutch Master® online!

New Commercial Edition® Cal-Mag® has been formulated using multiple high-end sources of select calcium plus magnesium, nitrogen, chelated iron and specialized select organic amino chelators that exponentially increase calcium uptake by binding and protecting it from other nutrient elements until delivered well inside the plant.  Calcium and magnesium, next to nitrogen, are the two main elements that cannabis is most often deficient in due to the plant’s insatiable appetite for them.  

Cal-Mag® will strengthen branches and increase dry weight while maintaining the correct elemental balance, especially for those strains of cannabis that exhibit the need for heavy Cal-Mag® feeding.  Calcium is also crucial to a plant’s defense against fungal attacks by resisting the internal spread of pathogens (root rot, bud rot, powdery mildew) due to calcium increasing cellular wall strength.  The calcium to magnesium ratio has been calculated to be most effective for a balanced uptake making Dutch Master® Commercial Edition® Cal-Mag® the strongest, most concentrated, best-value calcium and magnesium additive available!

Cal-Mag® is a super cost effective, vital additive for all growers and is designed to be used as both a root feed and foliar spray, with the lights on, to maximize uptake and help prevent calcium and magnesium deficiencies.  Remember - calcium is king!

The Dutch Master® Commercial Edition® is a range of advanced nutrients and additives suitable for both professional and general hydroponics growers and is proudly manufactured in Chicago U.S.A. under strict licensing exclusively for Dutch Master® Nutrients in an ISO 9001, ISO 13485 (medical manufacturer) and ISO 14001 (green manufacturing practices) certified facility - a world first in the cannabis community!

Usage & Mixing Instructions:

See Usage Instructions & Tips for in-depth root & foliar feed directions and advanced growing tips, and Feed Charts for recommended Cal-Mag® dilution rates.  Never mix undiluted nutrients or additives together as precipitation (fallout) will occur rendering some nutritive elements unavailable to plants potentially creating deficiencies.

Root Feeding:  Add separately to water while stirring, beginning with Sila-Guard®, then Cal-Mag®, followed by Micro, Grow, Bloom, Trich-XL®, Zone® then Saturator® last until you reach desired EC/ppm - measure preferably using a calibrated meter.  If you don’t have a TDS meter, be sure to follow our Feed Chart recommended dilution rates beginning with the standard feed chart before progressing confidently to the aggressive feed chart.  Reduce Cal-Mag® by 1mL per gal/4L for every 200ppm/0.4EC found in hard well or tap water.  To increase nutrient EC/ppm strength, increase dosage volume of Micro, Grow and Bloom maintaining recommended dilution ratios.  To decrease nutrient EC/ppm strength, dilute by adding more water.  Finally, check pH and adjust accordingly.

Dutch Master® recommends maintaining nutrient feed solution pH for Aqua Feed® and Media Feed® between 5.5-6.1 and Coir Feed® between 5.6-6.2 using Commercial Edition® pH Up or pH Down.  When making a fresh nutrient solution, adjust the pH to the low pH point recommended for your nutrient above, as pH may rise over time.  If the pH of your nutrient solution approaches the high pH point above, and it’s not time to drain and refresh the entire nutrient solution in the system, slowly add a little Dutch Master® Commercial Edition® pH Down while stirring and checking with a calibrated pH meter or pH indicator strips to achieve the low pH point again.  Remember, adding pH Down is also adding phosphorus, while adding pH Up is also adding potassium so be diligent with its use.  If the pH of your made up nutrient solution shifts drastically in a short period, it is usually a sign that the plant is stressing.  Check for root rot etc.

Foliar Feeding:  Foliar spray the top and underneath of leaves weekly with a combination of Sila-Guard®, Cal-Mag®, Trich-XL® and Saturator® mixed in water (never mix undiluted), pH adjusted to ~6.0-7.0, as per the foliar Feed Chart dilution rates, from cutting, all through the vegetative stage and up to bud-set (about 14 days into flowering), preferably when lights first come on, avoiding excessive heat and direct air flow on plants (turn off fans to allow spray to sit on leaves longer).  Spraying leaves until slight runoff occurs at the beginning of the lights-on cycle allows plants to maximize photosynthetic response to the foliar application resulting in faster, healthier growth!

WARNING:  Avoid spraying light bulbs or electrical equipment.  For the longest product shelf life, store nutrients and additives with a sealed cap in a cool, dark, dry area.
