Spider mites are going to be about the size of a pin head and u should see little white dots in your plants from them sucking out the juice from the leaves. If small webs, then yeah, definitely spider mites. They may also be white flys. If you see what look like little tunnels in the leaves then thats the larvae burrowing through your plant, feeding as they go. The damage is what should concern you. If the plant looks healthy then no worries.
