Salt from the air may be an issue, I'm not sure. I know cannabis is often grown right along the ocean in many parts of the world, though. As long as it's not so much that it's drinking up a lot of salt on a regular basis, should be okay. The wind will be fine, as long as it has always been exposed to it. Taking a plant living in still air and putting it into wind will ruin it, but a plant that has always been in such conditions will be fine! Unless there's a sudden gale force wind or something.
At next transplant, try and mix in something natural you can get your hands on, that isn't so dense. Even some ground up old dry moss or leaves would be good. Then it won't be so dense and clay-e. But as for nutrients, that soil probably has most of the right stuff. If you can/find get any worm poop ("castings") or maybe composted livestock manure, that would help. You can top dress (sprinkle and mix in), or wait until transplant, and add it then.
Aside from that, make sure she (hopefully, she) is getting as much direct sunlight as possible, and she'll continue to do well.
