I'm not plaesed with my MG. My next grow will be with a soil that has no nutes to start. I ended up bying 2 different soils for my grow(not much available in winter around here) first MG then I got a bag of Scotts Premium potting soil. I Scotts also had nutes but is growing the plants with what I feel is a better color and healtier looking leaves.
In this picture the back leaves are in the Scotts the blurry one in front is in MG.
