Again, the stunting and yellowing are identical with nitrogen deficiency (figure 2). In cereals, Molybdenum deficient plants appear to be limp (figure 3).

Photo 2. Tipburn of lettuce caused by calcium deficiency. Photo: Elsa Sánchez, Penn State. Iron Deficiency. Cause: The most common cause of iron deficiency is high pH in the media and/or irrigation water. It can also be caused by nutrient imbalance. Symptoms: Iron deficiency shows up in plants as yellowing between leaf veins. Look for this
Calcium is also used to help transport other substances across cell membranes. It is found in large quantities in cells that are dividing (meristematic cells), and this is the reason why calcium deficiency often manifests in the growing roots, shoots, buds and young leaves. The leaves of some plants hook downward and exhibit marginal necrosis.
Reddish purple margins are characteristic of phosphorus deficiency on corn. Symptoms usually occur on young plants when the soil temperature is below 60 0F. Deficiency symptoms may appear when soil phosphorus levels are adequate. When soil is cool, less phosphorus is available for plant uptake, whether or not an adequate amount is present.
Magnesium deficiency. Symptoms: Yellowing between the leaf veins, sometimes with reddish brown tints and early leaf fall. Magnesium deficiency is common in tomatoes, apples, grape vines, raspberries, roses and rhododendrons. Cause: Magnesium is needed for healthy leaves and for plants to harness energy from the sun (photosynthesis).
Calcium (Ca) is usually the dominant basic cation in soils, and only in acid soils with low CEC is the level of Ca likely to be so low that it limits plant growth. Strongly acid soils tend to be high in exchangeable Al, and the toxic effects of Al on root growth may exacerbate the symptoms of Ca deficiency . High levels of K and Mg may reduce
The presence of an insoluble form of calcium ions will impact the plant’s growth because it’s unable to absorb this nutrient. The presence of calcium bicarbonate causes a general nutrient deficiency, affecting the growth of pepper plants. It also leads to bicarbonate root rot and turns the plants chlorotic, where the leaves don’t produce
