I personally don't care for MG simplly because of what FreeWheelin' said,TO STRONG. Don't get me wrong it works great if you know how to mix it right for your plants, I've used it with great results. It takes patients that's all and very small doses. I have noticed before that if you don't flush at the end and stop fertilizing a few weeks before harvest my plants had a slight chemical taste but that was early on in my growing experiece and have learnd my lesson since, DON'T OVER FERTILIZE!:greenthumb::weedpoke:
