First Grow-Homemade Box-Bag Seed

So this is my first attempt at growing, i started my plants outside and after about two weeks brought them inside into my box. I want to get them on some nutrients but am not sure what nutrients to use, can anyone help me!!??

I hear General Hydroponics has a really good starter box for nutes. It is about $40 on Amazon. Hope this helps you, should have all you need, even comes with a feeding chart.
