It does look a lot like spider mites- the small white specks. Not sure about the larger damaged patches- maybe a different pest. If you can post more info maybe people can make better guesses. How to Ask for Grow Support
Also a couple more pics of the whole plant and setup wouldn't hurt. Good luck with it.
