awesome thanks for your reply, this is my first coco grow so its kinda new to me. and yeah they aren’t showing clawing or burning, just needed some reassurance.They look a little dark in the first pic. But overall they look healthy. When I started running coco years ago I noticed my plants were darker and didn’t yellow at the end of flowering even when I flushed for 2 weeks (Which is very long in coco). I wouldn’t worry about it, they aren’t getting the nitrogen claw look or burning.
you could always cut back a couple mills and see how the plants react
