well, i use miracle grow for tomatoes in the outdoor grow but ONLY at half strength of what the directions call for established plants and at one third strength for seedlings at least 3 weeks old until week 5 or 6...then the half strength begins. and this is done no more than once every 10-14 days! miracle grow can easily burn your plants if not diluted properly but if you follow the above directions faithfully you'll have large, healthy plants. switch to bloom or super bloom for flowering but also remember they're to be used at no more than half strength every 10-14 days.

fox farms is easier and safer to work with and delivers same results...it just costs a lot more...
