  • Causes of Calcium Deficiency in Plants, and How to Fix It ...

    Extreme weather conditions can also affect a plant's ability to absorb calcium and other nutrients from the soil. If you plant too early or experience a prolonged period of unseasonably cold weather, then your plants may suffer from calcium deficiency. High humidity can cause the same problem, for the same reason.
