Not sure why, but different people seem to have different results from different mixtures and products. So I am going to say when you are starting out you should keep it simple. Fox Farms is great if you can find it, but (cant believe I am going to say this), Miracle Grow seed starter is everywhere. You let your water sit overnight an then dont worry about nutrients while they are seedlings. Later, the more comfortable you feel you start goofing with your own mix or better premades. Never an all or nothing thing, just sort of feeling till you fall in love with one.
