Leaves Darken on the Tip
Leaves are dark on the tip. The tips appear brown in color. This is a form of necrosis called Leaf Tip Burn.
Leaf Tip Burn is almost always associated with a nutrient imbalance. This may either be due to an imbalance of a specific element or to a general overload of fertilizer. While the treatment is the same in all cases, you may still want to select from the list of additional symptoms in order to search for the precise cause of your African Violet's symptoms. Keep in mind, however, that due to the complex interaction between plant nutrients, pinpointing the precise cause will probably be very difficult. Often, an excess of one element will cause a deficiency in one or more other elements, and vice versa. Thus, short of sending your plant to a laboratory for testing, you will probably have to be satisfied with simply knowing that your African Violet suffers a nutrient imbalance without knowing exactly why.
