The leaf edge yellowing caused by soil potassium deficiency or potassium excess mostly occurs in the middle and lower leaves. Generally, the phenomenon of potassium deficiency is rare, and the yellow edge caused by potassium excess is the most common.
When the temperature is too low, the blade becomes brittle, and at the same time, the blade edge turns yellow, forming a parachute blade. If the temperature is too high, the water at the leaf edge will evaporate quickly, which may lead to the leaf edge burning, yellowing and drying.
Drug damage can also lead to dry edges.
It depends on the growth of the mushroom mother root system.
