Thanks

Looks like spider mite damage and eggs to me. I use a mix of pyrethrin and neem oil and spray every 3 days for 3-4 treatments or until they are knocked back. I do this only during veg. When flowers begin to show, hopefully you will have the spider mites under control and will not need to spray anymore. Check out GWE site tutorials to see other treatment options.
