My comment box upon activation is less than half the width of the center column. How can I adjust it to be full width?
Despite there not being a timely response - I was able to solve the issue and will share with anyone reading.
Once again, it was Jetpack. I disabled the comment section of Jetpack and the styling returned to normal. I had to "inspect code" via Google, then I searched GVectors for similar Jetpack comments to stumble on my solution.
Oh - and one of the glaring clues was the header above the comments "What Are Your Thoughts" is the default comment setting in Jetpack - if that helps you identify.
Yes, please never leave Jetpack comments enabled when you use wpDiscuz. Jetpack comment form inject wpForo form and crashes all functions.
