i'm not a nutes expert by far but i read the website last nite: if the nutrient analysis is correct, then it's low in Mg, no Ca, and alot of micros are missing. and no silica, no sulfur too.
Without double checking I thought that they had the same micro's just different ratio's. I forgot I typed them down. Just the sulfer and silica in the megacrop is different I guess. No biggy.
