Not to disagree with anyone or start an MG debate lol! bUT, MG works fine as long as it is handled properly. The key is in watering. As we know the nutes are activated by watering so the more you water the more you feed. To me this is quite a simple way to do things. In soil, small issues can be noticed sooner and corrected quicker than any other medium. I water the girls in my new grow, that I did in MG with MG perlite. As they tell me, if I start seeing any yellowish tint or other indications of under feeding, I know it is time to add some water. I just give them enough to lightly moisten the root ball, and the next day or so they look better. I will admit that I normally use FF Happy Frog, but the MG was all that was available. This was one of them at 4 weeks...So MG will work for you, just be careful...Good Luck!
