In over 90% of the “alleged” deficiency incidents that we have responded to (with FloraMax), the grower has either failed to follow the chart or maintain the correct environment. Deficiencies are only ever likely to occur if growers are underfeeding, or running excessive pH, PPFD, VPD or CO2. In the latter cases, add 1-2ml/L (4-8ml/Gal) of FloraMax Ca-Mg-Fe or Veg-1. If this fails to fix the problem within 1-2 weeks, then the issue is probably not due to Cal-Mag or trace elements.

NOTE: If a nutrient solution is deficient, Ca-Mg-Fe is the most effective and efficient 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.

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.
