Spuluka,
Thanks again for your help. I ended up opening a case with Juniper techsupport since the troubleshooting guides didnt pinpoint the issue.
Turns out (according to tech support) that policy based vpn does not support site-to-site connectivity for the dynamic vpn clients.
In order to allow dynamic vpn clients to see both sites accross the tunnel i had to change to a route based vpn for the site-to-site connection.
Thanks
