Answers:
I use Miracle-Gro as well but I don't have a hydroponic system. Truly, you only want to chemically enrich your plants once a week or so. The excess nitrogen in the food will burn and eventually kill them. I use the soil method w/ Miracle Gro soil, water my plants every other day (although twice a day while I'm attempting to germinate seeds, once a day during the first week of life). Use plain water the majority of the time to wash out the chemicals, and do NOT use any chemicals for the two weeks prior to cutting. I feed them with Miracle Gro liquid once a week (diluted to specifications, of course). If you DO choose to use the Miracle Gro with the hydro system, I would suggest diluting it 2X the reccomendation.
