These are NOT recommended for use as foliar sprays. Firstly, the calcium in Cal-Mag additives or 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, root enhancers 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 contains ingredients designed for uptake by stomata, not roots. 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. This will result in improved root and foliage growth, improved plant structure and increase the number and quality of bud sites.

The chemists at FloraMax have been able to deconstruct popular organic ingredients such as kelp, fulvic acid and guano then isolate specific ‘beneficial’ organic molecules. These are then incorporated into our additives in a purified and potent form. Importantly, this enables their concentrations to be optimized for maximum nutrient effect, with no negative side-effects. The result is a range of products that produce unique and tangible results without causing blocked drippers, pH fluctuation, build-up, foaming or odors.
