You didn't mention how you're growing it or what the pH of your media is.
Sometimes plants will do this during a rapid stage of growth and then get over it. Plant parts don't green up until light hits them. When a plant is growing rapidly, chlorophyl development might need a few hours to catch up. But keep an eye on things to see that they don't get worse.
Edit: Duh, you mentioned coco in the subject line! Anyway, maybe someone who uses coco has a better insight.

Kyle,
I am experiencing the same issue on my new growth. It’s identical to the issue above. And!!! I am using flora flex nutrients !
Did you find out the cause ? Did it get worse ?
