Benefits of Dolomite Lime for Cannabis
\n1. pH Stabilization
\n – Dolomite lime (a mix of calcium carbonate and magnesium carbonate) helps buffer soil pH, keeping it in the optimal range (6.0\u20137.0 for soil).
\n – Prevents acidic fluctuations, which can lock out nutrients.<\/p>\n
2. Calcium & Magnesium Supply
\n – Provides a slow-release source of calcium (Ca) and magnesium (Mg), essential for plant health.
\n – Helps prevent deficiencies like blossom end rot (calcium) or yellowing leaves (magnesium).<\/p>\n
3. Improves Soil Structure
\n – Enhances microbial activity and nutrient availability in organic grows.<\/p>\n
How to Use Dolomite Lime for Cannabis
\n– Pre-Planting (Soil Amendment)
\n – Mix 1\u20132 tablespoons per gallon of soil (or ~5\u201310 lbs per 100 sq ft) before planting.
\n – Works best when incorporated into the soil 2\u20134 weeks before use.<\/p>\n
– Top-Dressing (Mid-Grow)
\n – Lightly sprinkle 1 tsp per gallon of soil and water in if deficiencies appear.
\n – Avoid overuse\u2014it\u2019s slow-acting and hard to flush out.<\/p>\n
– Hydroponics\/Coco Coir?
\n – Not recommended\u2014use calmag supplements instead for better control.<\/p>\n

Potential Drawbacks
\n– Can Raise pH Too Much \u2013 Overuse may make soil too alkaline (>7.0), causing nutrient lockout.
\n– Slow Release \u2013 Not ideal for quick fixes; use gypsum (for Ca) or Epsom salt (for Mg) if fast correction is needed.
\n– Not for All Mediums \u2013 Avoid in hydroponics or inert substrates like coco coir unless pH buffering is needed.<\/p>\n
Alternatives to Dolomite Lime
\n– For calcium: Gypsum, oyster shell flour, or calmag supplements.
\n– For magnesium: Epsom salt (magnesium sulfate). <\/p>\n
Final Tips
\n\u2714 Test soil pH before applying dolomite lime.
\n\u2714 Use sparingly\u2014excess calcium can block potassium\/iron uptake.
\n\u2714 Best suited for organic\/living soil grows rather than synthetic nutrient setups. <\/p>\n","protected":false},"excerpt":{"rendered":"
