Iron availability to plants is reduced by a high concentration of phosphorus and also by precipitation of iron at high pH. Potassium helps with the movement of nutrients, waters, and sugars throughout a plant. Boron deficiency makes stem and leaves brittle, distorted at leaf ends and it tends to curl. Cobalt is a trace element in the plant because it is not been more essential for plant growth. a. In Brassica, the lamina is restricted and the leaves show cupping owing to the curling of leaves.

In monocotyledonous plants like cereals, Mn deficiency symptoms appear as greenish-grey spots, fleeks and stripes more on the basal leaves (Grey speck). Mn deficient occurs in plants that contain less than 25 ppm Mn. Blossom end rot in tomato is due to Ca deficiency so reduce in quality and yields. Magnesium not only reduces yield, but it can stress the plants too. White bud of maize: Soon after the emergence of seedlings, areas between the veins of old leaves become light yellow and develop white necrotic spots, which later develop dark brown necrotic areas that enlarge and coalesce, resulting in the necrosis (death of the entire leaf). Identifying symptoms of nutrient deficiency is not an easy task. Silicon deficiency causes physical stress such as drought, high temperature and chemical stress such as salinity, metal toxicity.

Fortunately, there are ways to identify and treat different types of nutrient deficiencies in your marijuana plants and encourage new growth. Decrease in the quality of fruits and vegetables. Certain plants such as anubias or java fern need lots of potassium to survive. Shoots remain short and thin with upright growth. Chlorine does not show interveinal chlorosis; it shows distinct chlorotic and necrotic lesions with the abrupt boundary between dead and live tissues. Silicon deficiency in plants causes the easy attack to diseases, pathogens and stress. Thin, erect and spindly plants with sparse and restricted foliage suppressed lateral bud production and reduces growth. Not all plant problems are caused by insects or diseases. In grasses, the lower leaves turn into brown beginning at the leaf tip and progressing along the midrib in the form of inverted ‘V’ shape. In later stage burning of the chlorotic leaves start from the tips and margin, spread inwards of leaf in plants. Leaves become leathery in texture and veins form a brown netting and it can be characterized by burnt tips, development of chlorosis and necrotic patches on leaf margins and cambial activity is checked.

Due to the high mobility of N deficiency symptoms first appears on the older leaves in the form of light green to pale yellow in plants. In mild deficiency cases, Boron deficiency develops whitish yellow spots on the base of the leaves. The most notable symptoms of potassium deficiency in plants are browning, drying and curling of the tips and edges of the recently matured leaves.
