Hey everyone, my first grow ever, My indoor seedlings are doing well and are almost two weeks into the veg stage. I want to get fertilizer so in about another week I can slowly start the feeding regimen. I know that in the veg stage i need a higher N value in NPK. I was going to go to Walmart to get this, any leads or advice on what I should buy? I'd like a powder or liquid mix or something I can just mix into the gallon of my distilled water. I'l like cost to be a factor as well as I am on a budget.
