Your first bad move is fox farm ocean forest soil, that soil is crap. Try roots organic, or maybe even some promix with coco in it. I've heard fox farm ocean forest was to hot for clones, i've also saw a lot of videos on how bad it was. Second if you can, dont grow them in pots if you have them outdoors. the thing about outdoors is you want them to grow as big as possible, and they will if you dont contain the roots. They naturally grow outside anyways, it wont hurt them. Maybe you could dig up some dirt and add some fresh soil in to jump start them. 3rd growing in a swamp is a horrible idea, not only do you have to worry about mold but the amount of insects living around the water and animals could be fatal to your girls. In a swamp you wont be able to control the humidity, they might do good in veg but when they start to flower they might not do so good, you dont want to put all that time and effort in it for nothing. If you do decide to do it your way let me know how it turns out mate.
