Deficiency of calcium in plants causes reduced internode length and crinkled leaves.
Initial signs of calcium Deficiency include localized tissue necrosis that stunts plant growth and causes young leaves to curl or have necrotic leaf margins, and terminal buds and root tips to eventually die. New growth and tissues that are expanding quickly on the plant are typically the first to be harmed.
- These include boron, copper, iron, manganese, molybdenum and zinc. Most nutrient deficiencies are caused by a lack of nutrient content in the growing medium or nutrient solution
- Plants require calcium in order to develop new growth points and root tips. Symptoms of a deficiency include decreased growth in new leaf, buds, and roots. Younger leaves curl downward and develop tip burn, which is the browning of the leaf edges and tips.
