GHE is my tried and trusted outdoor nute brand. This was my first time indoors with BioMarine and it caused my tent to stink to high heaven. Overall I think when combined with some microbugs, this stuff really shines.
Not a whole lot to say about this brand. I think filtered tap water would have worked just as well for me. My tap runs at 250ppm so I don't think this was strictly necessary.
Overall I had issues with this plant being in lockout for too early, too long. It really preferred pH at 4.5-4.6, drifting above 5 gave me symptoms of lockout that I was unaware of until it was too late to correct.
