Why Are The Tips Of New Growth Turning Yellow?

Could someone advise on why are the tips of new growth turning yellow and what I can do to save them? Yellowing of tips in new growth happens when your plants have a deficiency in some of their nutrients. The most common cause of this is a lack of potassium.

Potassium is one of the most beneficial nutrients in a plant.  It provides the plant with the ability to withstand drought, cold, and other environmental stresses. Potassium is also essential for healthy growth. The concentration of potassium in soil affects the development of roots, stems, leaves, and flowers. Potassium is an essential component of cell membranes, enzymes, and chlorophyll, as well as other important elements that make up plants. In this way, potassium has many benefits for your garden.

Potassium is found in several forms in soil. It can be stored in the soil as insoluble compounds, such as calcium and magnesium, or it can be bound to amino acids and proteins in the soil. The amount of potassium in the soil is affected by several factors, including the pH and organic matter content of the soil. Potassium in soil may also be lost through leaching or volatilization.  Plants absorb potassium from the soil through their roots and then use it for growth. Potassium in the soil can be lost to the air and water through leaching. Leaching occurs when water moves downward through a porous medium. When the soil is wet, potassium moves down through the soil as well.
