Hey, you do know some fade on the fan leaves is normal right? It's perfectly fine for the plant to start eating stored nutes as it nears senescence.
I was unsure of your timeline
I too am playing in Coco a bit. It's different than straight soil and requires attention. Don't worry to much, your crop looks well enough to take care of you.
