What are the symptoms of calcium deficiency in plants ?

Calcium insufficiency manifests itself first on younger leaves and tissues, with stunted growth and a bushy look. The youngest leaves are often tiny and malformed, with brown chlorotic patches growing along the borders and finally uniting in the middle. Leaves may be cup-shaped and crinkled and the terminal buds deteriorate with some breakdown of petioles. Veins are also brown, making the black veins of fully necrotic leaves a common trait of Ca-deficient plants. Crinkled and torn leaves are also possible. In Ca-deficient plants, root tip development is inhibited. Under severe deficiency ,dessication of growing points of plants occur.
