Site Origin Widgets Bundle and Page Builder Slow Down Website Speed

Hello, My website has begun moving incredibly slowly so I deactivated all of my plugins and reactivated them one by one and ran a scan to see who is the culprit using https://gtmetrix.com. It has been determined that when I have both Site Origin Widgets Bundle and Page Builder activated I receive an F but when I deactivate them I get an A. I am using the Gaea theme for 1.5 years and these plugins are what govern the entire aesthetic appearance of the site https://motl.org so without them the entire look of the site is terrible :( Any idea what is going on?

Thanks so much for your help!
