Column width and position issue

Hi, I’m noticing a column width and position issue on my homepage https://theregenerations.com

I’ve attached a picture below. On any page I have where I use the 2/3 + 1/3 layout I find that my text box is 439px and 1px offset to the right. The blog boxes underneath only have a width of 438px on my monitor.

Could you take a look please and see if there is a simple solution for this?
Many thanks
Greg
