miracle grow is it bad?

i am wondering if i can use this on my plants

Do you have Miracle Grow fertilizer or soil?
I started with miracle grow a few years ago, but wasnt very happy with the results. Some plants will handle it better than others, so results also depend on what you are growing.
Now Im using Fox Farm soil/nutes and I have never been so happy. If you can find some, I would recommend Fox Farm.

kay cuse i just started my plant on it and i think it burned it ! so i aint to happy cuse she was beginning to be a beauty ! i followd the instructions but i am just a lil pissed so i flushed her out and hope to see what happends
