SSL with EV on multisite network

Hi
I am facing some issue with SSL cert with EV on one of my network domain: globalgreenformula.com

Main domain: http://www.asiaformula.com - SSL showing
Other domains: http://www.emarketplace.asia - SSL showing

I have recently bought new domain: globalgreenformula.com and mapped with http://www.asiaformula.com/globalgreen

should i buy SSL for http://www.globalgreenformula.com?

Thanks
