pretty sure there like FF whre yo have to use half of what they say, but could be wrong...
if you can work out elemental ppm from the ingedient labels and how much you feed that will tell you what you need to know. looks like a money-sink to me as i look over that schedule. overly complicated to sate demand of the masses but in the end deficient in something so you have to buy more stuff, lol...
again, if you work out the elemental ppm an dcompare to some common, proven formulas and it balances out, everything i said is totally wrong. make a spreadsheet like i did in my week 5 ggxww diary. the formulas aren't there, but ...
as exmaples only, here's some formulas i found googling
