Narrative:

I was working malibu departure sector. Aircraft X was run down by lax tower for departure from smo. In my rundown list for departure from the lax north complex was aircraft Y heavy. Normally lax sequences smo departures with the lax north complex departures. In this case both aircraft tagged up within seconds of each other and separation was lost almost immediately. I recognized the problem and promptly turned aircraft X twenty degrees to the right to establish divergence. Separation was established and both aircraft proceeded without further issue. Neither aircraft mentioned an issue. Recommendation; further training for lax local controllers. I also believe that a new; safer departure procedure should be established for smo.
