The leaves look relatively healthy. I am wondering if they aren't getting to much water? How often do you water? What kind of soil are they growing in?
I am not familiar with growing conditions in Texas. Maybe Dave or Trish are growing 'Autumn Joy' and can tell us how they grow theirs.

The stems are looking a bit etoliated, might not be getting enough sun.
Too much water and not enough sun can cause the stems to be weak, and fall over.
