What Happens When Plants Get Too Much Potassium? Hunker

The primary risk of too much potassium is a nitrogen deficiency. This will stunt the growth of the plant and lead to chlorosis, a yellowing of the foliage that first appears on older growth lower on the stem. The veins on the leaves will have a red tint. Newer leaves will be smaller in size. These effects can be countered by adding compost or
