Hey buddy. Im quite new to this and still learning, but going by the second pic the bottom pot looks quite dry. To the best of my knowledge coco(if coco) should never be to get too dry, it is very hard to rehydrate. And the plants are a little pale, maybe not getting enough nutrition? Like I said Im still new and learning, so it might be better to get some advice off someone who is more knowledgable on this, or do some research on the site. Good luck with the grow.
