sir_isOanswered grow question 4 years ago I've seen some similar things, likely genetics and conditions.
It's not necessarily overwatered (at least it doesn't really look like it to me, but I'm assuming the very light/bright green is just the lighting/photo), simply the fact that those sort of plants often have much heavier/thicker leaves, which of course is affected gravitationally, but they also often have a tendency to curl.
Keep that in mind when trying to "gauge" the health of the plant.
So, assuming you are giving the plants the same amount of water roughly, it shouldn't be overwatering. And assuming those plants look darker green IRL, you shouldn't have to worry much.
