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.

I grow in coco also and that looks good. That yellow you see near the bud will darken up real quick. So don't panic keep feeding and watering.

The second photo may have some bleaching. Hard to tell cause it's not in focus. Is the bud tip white? Do you use co2? What type of light?

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 ?
