Lazy leaf structure, looks like every leaf is just sitting around like a bunch of disorganized lazy workers. Just chilling.
Water is responsible for turgor pressure, which is part of water cohesion within plant from root to leaf, when water is cycling efficiently leafs will be sharp, upright and have a disciplined look to them, it's not good or bad, simply a Indicator of how much work is being performed by a plant.
As it deals with more moisture there is more suction created, this suction builds Into tension within the plant.
When a plant's leafs look lazy and unsure it's a sign of not much is getting done in terms of total respiratory capacity. There is not much suction therefore not much water cycling.
Your daytime temps are 70 which is far from optimal temperature for photosynthesis to occur in general.
