Centering Easy Columns on a WordPress Page

Hi, I am trying to figure out how to center Easy Columns columns on a WordPress page (using Spacious business theme).

I found one post on this topic, tried what was suggested, but nothing changed. Any help is appreciated. It’s a great plugin, but the slightly off-center columns (left-justified?) are making me a little bonkers. 😉

Here’s the page: http://talinisnursery.com/?page_id=11

Thanks!
