What typical symptoms appear when flowers are deficient in calcium?

Growing points are damaged, and in severe cases the growing points die, showing a "broken neck" symptom; the growth of root tips and apical buds stalls, young roots become deformed, the root system shrinks, root tips die, and root hairs become distorted, some appearing scale-like, with few roots; young leaves lose their green color and become deformed, often taking on a hook shape, with leaves wrinkled, leaf tips twisted, leaf margins curled and yellowed, and in severe cases new leaves have difficulty emerging and may even stick to each other; leaf margins develop irregular tooth-like cracks and necrotic spots appear.
