Primary nutrients Nitrogen deficiency results in very stunted, spindly yellow plants or yellow leaves, sometimes with pink tints. There is a general yellowing of older leaves (bottom of plant). The rest of the plant is often light green. There are elongated twisted leaves on cauliflowers or other brassicas (cabbage family) growing in alkaline soil. Molybdenum deficiency is normally seen in cauliflowers and brassicas, particularly when growing in insufficiently alkaline soil.
Everyday, simple reasons, such as fatigue from overuse, can lead to temporary, acute cramps in the hand. Hand cramps are usually brief, but they can be severe and painful, and sometimes accompany a tingling or burning sensation (paresthesia).
Cramps in the feet, hands, arms, abdomen, and along the rib cage are also very common. Muscle cramps are common and may be stopped by stretching the muscle. The cramping muscle may feel hard or bulging. Muscle cramps are different than muscle twitches, which are covered in a separate article. Muscle cramps are common and often occur when a muscle is overused or injured.
