Sheffelera Problems

Sheffelera Problems

Sorry I don't have a picture to make this easier, but... I have a large (about 5-foot) Sheffelera in my living room. Some of the leaves are turning black at the tips. Otherwise the plant is super healthy. None of the leaves are fading, there are no bugs, and there is no wilting. Does anyone know what I might be doing wrong? Thanks!
