MG soil is far worse than MG nutes. I have used MG nutes and won't again. But the real MG problem is the soil.

MG soil contains fertilers that are time released and thus you have no way to control the feeding....as everytime you water, you nute.

MJ doesn't need or want nutes evertime its watered.

MJ doesnt need or want timed release nutes.

Why would MJ need or want nutes as a seedling and even up to week 3???

Over ferting I suspect is the cause of more MJ grows problems than all others combined.

There are some strains I suppose that will indeed flourish under these conditions. But they are the exceptions and not the rule.
