I think that the fact that the leaves are laying on the edges of the pot is due to the fact that the pot and the leaves are on the same level , if the plant grow taller ( and she will during the stretch ) , the leaves will have nothing to lay one. That fact isn't caused by an issue with that plant. However if you can spot a lot of branches under the canopy then why don't you try a topping on this one ? It will slow a bit the grow but if it's well done it will provide you a nice little bush 😊👍
