All About Nutrients and Additives

I came across this wealth of info on nutes and additives and thought it worth of RIU. Here's the link http://www.igrowhydro.com/InfoSheets/InfoSheet-Nutrients.pdf

it comes off as a little pitchy but unbiased. there's a lot of good info in there about all these additives and what they (supposedly) do. the sheet does have its share of nonsense though. a lot of regurgitation of various company's sales pitches, but a lot of good info nontheless.

I agree, it's a combo of regurgitation mixed with personal experimentation. It is from a hydrostore after all. Perhaps it's best to post in the newbie section for people who are at a loss when starting out.
