I definately wont argue with Pman on coco growing as he has it mastered. I can tell you that MC doesn't act the same way as other nutes. There is no mention on their site to start off low in any medium, including rdwc and aeroponics. I think it's a lot more forgiving and their calculator for the most part is spot on.
The starting dose is low as it is since we are only talking 2g/gal (4L approx) at the seedling stage. It's something you need to tinker with as you get comfortable with it.
