Tamron 150-600 f5-6.3 question

I have noticed that my Tamron 150-600 f5-6.3 has not been producing fully sharp photos. Some photos have random lines, when I crop photos or zoom in on the photos slightly. You can see an example of this in the image below, although on some images, the same thing happening to the grass, happens to the wildlife I am photographing. Is this normal, and if not, what can I do to fix it?
