Cal-Max by Grotek is an additive made specifically to cover mineral deficiencies such as calcium, magnesium and iron, which tends to happen when you use water with a low EC such as osmosis or distilled water.
Signs of nutrient deficiency in your plants tend to show up after quite a while, so your plants can be quite sick for a while and you’d never know it. This is why it’s always a good idea to make sure this doesn’t happen instead of dealing with it when it comes up – simply add Cal-Max to your pure water as a preventive product.
You can also use it to correct nutrient deficiencies that have started showing – we recommend using it via a spray bottle for this particular treatment, as it gives much faster results.
Cal max by Grotek only contains the best quality ingredients that dissolve perfectly in water. It can easily be used in any sort of automatic watering system. It’s compatible with any growing medium, such as hydroponics, NFT, aeroponics, soil and coco coir.
ATTENTION! Grotek has drastically renewed its line of nutrients and has also formulated new compositions for the entire range of products, even changing the name of some of them. CAL-MAX (2-0-0 NPK) has not changed.
