What is the url to have a user go to their own dashboard from the main site?

Hello WPMUDEV team,

So after a user has already registered to my multisite to have their own blog, and they login, they are redirected to the home page of my site. I have a link there to go to the dashboard.

What i want is for it to redirect them to their own dashboard, rather than the main site dashboard. I am assuming that its something like http://www.mysite.com/%username%/wp-admin/

Right now i have it set as main dashboard and they get a page telling them they are trying to go to the main site dashboard, which they do not have access too, and below gives them a link to their own dashboard. So i want the link to skip that page and automatically send them to their own dashboard.
