These are the kinds of plant food I've used my whole life. I'm only 19 but whenever my mom would plant stuff she'd use Miracle Gro. That said, I was wondering if this would be okay for certain types of strains, or if it would work for all strains. I'm planning a relatively small (five seeds to start) indoor grow, and I've already planned out most of it. The only concerns I have are related to nutrient problems, like what types work the best to get a high yield. So, is Miracle Gro a good choice for the cultivation of mj (not medical grade)?
