You should have a local grow shop...look it up in the hydroponics section. Fox farm has great products
I love the ocean forest soil. Has everything u need to start. Just don't use it for Ur seeds it may burn them.
There is enough nutes in ffof for about a month. Then i would recommend the fox farm line. Really cheap on amazon
If u can't find it local. I wouldn't recommend using nutes that aren't meant for cannabis.
