Ionic Cal-Mag Pro is an additive that can help deal with common deficiencies in intensive grows. After vigorous growth, plant foliage can become pale and yellow as the calcium and magnesium runs out. While any media is open to this, lots of coco users experience this kind of deficiency.
Ionic Cal-Mag contains lots of ingredients that are beneficial for plants, as well as the calcium and magnesium. The calcium is present in 3 different forms for rapid assimilation, which means it will get to work quickly. There is also iron in chelate form for helping deal with uptake issues and deficiencies. It also has L-form amino acids to assist photosynthesis and protein production. Finally, Ionic Cal-Mag Pro has seaweed extracts for boosting disease and stress resistance.
Always give nutrients and additives a good shake before using. This will ensure all of the ingredients that may settle are back in the mix when pouring it out. Add each product to the nutrient tank one at a time, giving a good stir in between. Never mix concentrates together in neat form as they can react badly, causing clumping of some elements. This can cause malnutrition or ineffectiveness and is a waste of nutrient! We would always recommend following the manufacturer’s instructions for best results.
