- Commonly occurs in hydroponic systems with soft water.
What it is / How it shows up:
Calcium deficiency is often discussed in cultivation forums and reviews, especially where growers troubleshoot plant health issues. It affects cannabis growth by disrupting cell wall formation, leading to symptoms such as stunted growth, yellowing of leaves, and necrotic spots. This deficiency is more prevalent in systems using soft or distilled water, which lack sufficient calcium.
How it’s measured or identified:
- Visual inspection of plant health and leaf colour.
- Soil and water testing for calcium levels.
Use in context:
- "Calcium deficiency is causing my plants to yellow and wilt."
- "Switching to a calcium-rich nutrient solution helped my plants recover."
