Future Harvest Organic Magic and Calnesium bottles

 ⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀

Either Calnesium or Organical Magic are a necessary additive to introduce into your feed schedule. Without one of these supplements your plant is likely to suffer a Calcium or Magnesium deficiency.

⠀⠀⠀⠀⠀⠀

This looks like: 

 

Magnesium Deficiency: Magnesium deficiencies are common in soils with a low pH (7 or lower). 

How to Detect: lower leaves will turn yellow and eventually dark green. Eventually, as the deficiency worsens, younger leaves will begin to be affected. After a while, the leaves will curl upwards and fall off. 

 ⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀

Calcium Deficiency: Calcium deficiencies will appear on leaves that are either new or still growing. 

How to Detect: Dark spots on new or growing leaves. Older leaves may die and new leaves will grow in small. Leaf tips may curl and brown spots will develop. 

 ⠀⠀⠀⠀⠀⠀

If a calcium magnesium deficiency is not addressed it can quickly turn fatal with your plant losing most of its lower leaves. When using nutrients designed for cannabis your plant shouldn’t suffer a calcium magnesium deficiency. However, this can still happen if your pH is out of range. The pH in your plant’s root zone is incredibly important and a pH out of range can cause the roots to not be able to absorb magnesium. 

 ⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀

Both Calnesium and Organical Magic will help to inhibit blossom end rot by providing that additional Calcium and increase your plants nutrient uptake.

 ⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀

Supplementing with Calcium Magnesium is especially important for growers who are growing in coco or reverse osmosis water (RO). Both coco and RO water contain little to no calcium or magnesium so it is crucial that growers supplement their plant with the extra cal-mag it will need.

 ⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀

How much cal mag your plant will need will be dependent on a few factors: strain, type of water used, water PPM, growing medium, etc. For example, someone growing in nutrient rich tap water may need little to no extra cal mag even when growing in coco. Others may need to add it at full strength. Every grow and plant is different so we recommend tweaking our feed schedule to ensure you find the right balance for your plant. In general, we recommend 1.5-5mL per 1 gallon of water. Commonly, coco growers will require more cal mag than soil growers.

 ⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀

Foliar spraying is a great way to give your plant an instant calcium or magnesium boost.

Foliar Spray Recipe:
⠀⠀⠀⠀⠀⠀

Green Up

Most yellowing plants are from deficiencies in either nitrogen, magnesium, or iron.  Calnesium contains all 3 and applying through foliar feeding will provide these crucial elements while any deficiencies in the root zone are corrected. 

- 2 ml Calnesium (Can be substituted for Organical Magic but you will lose the nitrogen boost)

- 1 ml Super B+

(Per Liter)⠀⠀

 ⠀⠀⠀⠀⠀⠀

Organical Magic and Calnesium will strengthen your plants cells and tissues which will increase your plants resistance to stress. Many of our growers combine this with Super B+ for out of this world stress relief!

Calcium and Magnesium will provide your plant with increased flowers, increased water, nutrient, and carbon dioxide uptake, and increased cell division, plant tissue development, and chlorophyll production. 

 ⠀⠀⠀⠀⠀⠀

You can use these products throughout your entire plant’s life cycle which includes rooting, vegetating, and flowering. It can be used as a foliar spray as well and can be given to your plant every feeding. 

 ⠀⠀⠀⠀⠀⠀

Both Organical Magic and Calnesium can be used in any grow medium: soil, coco, hydroponics, aeroponics, etc.

Why we made Organical Magic:

Future Harvest sees the need for quality organic nutrients in the market. Many organic growers were looking for an organic Calcium Magnesium product and coming up short. We searched the world for a source of naturally occurring Calcium which would be 100% soluble in water. To complement this calcium we also found a source of mineral based Magnesium. Together these ingredients make this product an organic source of Calcium and Magnesium. We went a step further and got this product fully OMRI certified to ensure your peace of mind when growing organically. Organical Magic is 100% certified for use in organic growing.
