I like MG myself, I've grown with nothing but MG MC and have had great results! The trick, as sketchbomb would agree with is, getting the nutes already in the soil, out but where I disagree is, to where. Don't flush out the good stuff, use it! Miracle grow has a reputation both bad and good for using chemical ferts in organic materials, good idea for roses and azealeas but not so much cannabis. Cannabis ravages soil and the roots deprive even the best of soils, quickly! Fortunately, this soil will stay a steady 7 on the Ph because it's basically all peat moss! Blast it with potassium nitrate, 7.1 ph. Flush with filtered water, 6.9 ph. Nothing will change that, except microbes. MG gives you excellent soil structure, moisture retention and a balanced ph, dont worry about the non-existsnt N-P-K values on the bag. Keep the soils natural processors happy and i guarantee you will have a happy plant. Add banana peels to the soil before planting, mix in some strawberry flesh, mango peel, egg shell. Mix a gallon of rain water from a lightning storm with a cup of beer, a drop of ammonia and a dab of ivory soap. These things will keep the "good" bacteria in your soil and keeping all of your micro nutrients from "locking up" and eliminating nute burn. I'm not telling you to use these techniques that I have used for years, many from my family whom had been in the tomato, corn and bean industries for generations but to give MG an honest chance and to understand soil "mechanics" before you run to Fox Farms or one of those fancy smancy organics companies and get burnt in the process...no puns intended!
