Well I use ocean forest but again its too strong for seedlings bla bla bla but I use fox farms happy frog(soil not nutrients) and fox farms light warrior but for all intensive purposes and easy access you could go to any near by Lowes or walmart or any department store like this that has a gardening center or supply and get any soil you can find that says seedling mix, light mix, seed/cutting mix etc right on the bag your good to get u through this time until your ready for nutes then I'd transplant them into ocean forest or what u use now...
