I could use some advice.

Hi i'm not new to growing but i am new to my med card. Learning slot more stuff. Well any ways i got dumped off 4 fem veg plants 2 have survived but if I'm not care full another one will. First thing i did. I poked around the dirt and i noticed that it was getting root locked. So i did the best that i could with what i have. I use good rich soil that my sister had but it's been out in the weather. So it's ?? So when I transplanted then i noticed that the soil it was in was no good. So i knocked off as much as I could. I don't add water cause it was already moist. 2 days go buy i water the second day but not too much. Only thing i haven't done is add nutrients and check pH. Anyways the 2 plants are turning yellow and curling. I found out that the plants were already growing outside so I'm thinking time to father nature. So i now have them in my closet awaiting some light and some nutrients. Wandering what i should do and hopefully cheap .

What you are seeing is not root locked/bound
Any pot will give the appearance of roots wrapped around the outside edge of pot
Root bound with cannabis is rare in fact many people have grown impressive plants in only a beer cup
