\nA plant having yellow leaves with dead spots likely has a deficiency of Potassium.
\n<\/section>\n
\nPotassium (K) is a mobile nutrient in plants. Deficiency symptoms typically appear first in older leaves because the plant translocates potassium to younger, growing tissues. Common symptoms of potassium deficiency include chlorosis (yellowing) along the margins and tips of older leaves, which progresses inwards. As the deficiency worsens, these yellow areas often develop into necrotic spots (dead tissue), giving the appearance of scorched or brown margins and tips.
\n<\/section>\n
\nMagnesium (Mg) deficiency also causes chlorosis but typically results in interveinal chlorosis (yellowing between the veins while the veins remain green). Nitrate (Nitrogen) deficiency causes general yellowing of the entire leaf, starting with older leaves. Phosphate (Phosphorus) deficiency can cause stunted growth and sometimes purplish discoloration, especially on stems and the undersides of leaves, but not typically yellowing with marginal necrosis.
