From what i look with your pictures, your cages size is ok for now but you need to add more horizontals branches and perches. I dont know what bulb or basking spot you have.

Can you show pictures of the entire cage setup (with the bulb brand and wattages)? so far they look a bit exhausted maybe this is juste because of the picture but my philosophy is better to be safe than sorry
how do the poop look like (texture, Color and frequency) and if possible grab a video when you pinch the skins over the belly (skin texture.. soft wrinkle are good indicators
