Looks good to me. Do not look stressed. Probably just genetics.

Agree with @SausageMahoney. A little fall fade and coloring. The plant looks close to the harvest window. :love_you_gesture:

Thanks for the feedback! I was hoping that was the case. The leaves remind me of leaves turning color like the trees in our area do in the fall.
