Leaves go down at end of day

Someone on here said its pretty normal with some auto's but Iv never heard of it.What you growing in because it almost impossible to over water coco the air exchange is that good.Jorge Cerventes Quote but it does look like over or under water.Maybe matey was right,he seemed pretty experinced unlike a lot of people that comment.If its soil then everyday must be too much with a pot and plant of that size.If that soil twice a week would be a lot until the plant gets bigger.Let the top of your medium dry slightly.Its the biggest mistake in growing.
