Do u mean the petiole? From the stem to the leaf blades? If yes then this is pretty normal. Its when the entire main stem and branches turn completely purple and rigid is when there's an issue.

You are low in nutrients. They are asking for more food :) Start giving them a higher PPM and make sure your PH is in the right range every time you feed and they will green right up in a week or two.
