The Cannabis plant is a calcium lover. Of course, this could all depends on the specific strain your are growing.
However as a good rule of thumb, most weed growers will suggest to add a supplement of calcium to their soil growing medium.
Simple enough, but:
How to add calcium to my soil ?
- Use easily available dolomitic lime (also called dolomite lime). It can easily be found in most hardware stores.
- Always make sure you use a rich soil mix (Such as ProMix or AgroMix) containing micro-nutrients.
- Mix approximately half a cup (1/2) of dolomite lime for about 5 gallons of soil.
- Blend and mix thoroughly
Note: by using our NPK Mix kit, you do not have to worry about calcium or magnesium deficiencies, as it is provided with our CALMAG fertilizer, an ideal 2:1 ratio calcium and magnesium nutrient supplement for cannabis cultivation.
