Description

Cal Max by Grotek Covers Essential Nutritional Needs of Cannabis Plants

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.

Cal Max by Grotek Features

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 be easily used in any sort of automatic watering system with 16 mm irrigation pipes. It’s compatible with any growing medium, such as hydroponics, NFT, aeroponics, soil and coco coir.

Dosage and how to use Cal max by Grotek

Watering:

  • Add 1-2 ml per liter of nutrient solution.
  • If you measure the EC you’ll be able to adjust the level easily.

Spraying:

  • Dilute about 1 ml per liter and spray both sides of the leaves.
  • Remember to spray when the light is low of the leaves could burn – before sundown outdoors and before you turn the lights off indoors.
