Hey Growmie,
If you have mites you'll start seeing bronze- or yellow-colored spots on the plant leaves. You may find that the underside of your plant leaves is discolored or that the leaves have small holes. Another early sign of spider mites is finding webbing on the leaves and stems of your plants. If the plant does have spider mites you're going to want to get it away from any other plant so they don't get them, if you caught it early the plant should be able to be saved. But I'm not going to lie it looks more like a deficiency than a spider mite infestation.
