Potted Plants to the Ground

hello everyone I got 4 jedi kush plants in quater gallon pot and there about 8 inchs in there almost month old, in foxfarm soil but, recently I got laid off so I really don't have income to buy 4 20gallons worth of the soil so I was wonderin if I can go get some natural native soil I know about that has traces of mineral clay in inand just use that instead of fofarm but if I don't use the native soil and straight dirt in back yard will my plants get affected from that, also I would like to added that I have all my nutritons already so couldn't just planted in dirt and treat nutriotion deficeny... If everyone could give me there opnion it would be great

as long as you got the nutrients, and you are planning on putting them into the ground quicklike....then all i would buy is a bag of perlite and ammend your plantholes with a mix of 2-3parts perlite to every 5-6 parts natural soil, make your holes huge, the bigger and deeper you ammend, the better and easier it is for roots to grow through. nature has a good way of balancing outside plants for the most part, just make sure they have food and plenty of drink and you will be good to go. NOTE: you could plant the fuckers right in the ground but the perlite would help the roots thrive and grow WAY quicker .... GL !!!!

if there is a shit ton of clay just go out and pay a buck or two a bag of some cheap all purpose potting soil and replace the holes with the potting soil and the perlite.........
