FloraMax Ca-Mg-Fe

Ca-Mg-Fe prevents plant nutrient deficiency symptoms, especially where “high pH” waters are used or when nutrient solutions are subject to volatile changes in pH and EC.

• Ca-Mg-Fe helps prevent or cure leaf yellowing, leaf curl, stunted growth, withered fruit-set and bud rot.
• Unlike other cal-mags, Ca-Mg-Fe also contains the full spectrum* of trace elements:
  1. Many base nutrient formulations are deficient in trace elements.
  2. Most nutrient deficiencies are in fact due to trace elements.
  3. Many trace element species destabilize when subjected to hard or “high-pH” water however, Ca-Mg-Fe contains alkaline-resistant compounds that cope with pH levels up to 10.
     *Iron, copper, manganese, zinc, molybdenum and boron
• Ca-Mg-Fe is 100% compatible with all liquid or powdered base nutrients that are deficient in cal-mag or essential trace elements.
• Available in larger pack sizes – 1L, 5L, 20L, 220L and 1,000L – suitable for large scale commercial applications.
• Dosage: 1-2ml/L (4-7.5ml/Gal) during veg and flower.

NOTE: Avoid using Ca-Mg-Fe with VegaFlora A+B or Veg-1 as these elements are already included and an excess will likely cause complications.

When using FloraMax, do I need a “cal-mag”?  No, the FloraMax line is designed to eliminate the requirement for additional “cal-mag” additives as its built into our base nutrients and Flowering Enhancer product.  Over hundreds of test grows during the development phase there was never any need for a dedicated cal-mag additive. Furthermore, use of additional “cal-mag” may result in excessive calcium precipitate leading to clogged lines or build-up in the reservoir.

Why then does FloraMax manufacture a “cal-mag”?  

To address the deficiencies found in competing brands.  We are committed to helping growers achieve their best results regardless of the nutrient regime they follow, our Ca-Mg-Fe product is ideal for use with other regimes.

Nutrient deficiencies? 

Over 90% of the “alleged” deficiency incidents that we have responded to (with FloraMax), the grower has not followed the chart. For example, the plants are in week-4 veg but are still being fed the week-2 veg schedule. Why? Sometimes growers are hesitant to advance the schedule to successive weeks.

High pH and humidity, and under-watering are other common causes.  If this is not the case and the nutrient solution is in fact truly deficient under the given conditions, employ Ca-Mg-Fe at 0.5ml/L (2ml/Gal). If that fails to fix the problem within 1-week, increase its usage rate to 1ml/L (4ml/Gal). If that fails then the issue is probably not due to cal-mag or trace elements (Fe, Cu, Mn, Zn, Mo or B).

NOTE: If the nutrient solution is deficient, Ca-Mg-Fe is the most effective way of rectifying the issue. Increasing EC by increasing the base nutrient dose is a common remedy, however, the most likely elements to be deficient in ‘most’ nutrient solutions are those contained within Ca-Mg-Fe – and is therefore why we recommend it for this purpose.

Can cal-mag additives or base nutrients be used as foliar sprays? 

These are NOT recommended for use as foliar sprays.  Firstly, the calcium in cal-mag additives (and base nutrients) will cause white staining on the surface of foliage.  During daylight (lights-on), this can hinder photosynthesis and cause burning of foliage (aka “necrosis”). 

Also, the nutrient species used in cal-mags or base nutrients are not ideally suited for uptake via stomata.  For maximum uptake and efficacy, it is best to use a specialized foliar spray such as FloraMax Clone Spray.  This can be used for seedlings and clones, then throughout veg and in early bloom through to about week 3 or 4 – but generally not later than this.  The ingredients in Clone Spray are designed for maximum uptake via stomata and will impart the necessary benefits desired from a foliar spray e.g. improved foliage growth, increased number and quality of bud sites, improved plant structure and increased root mass.
