If I remember right, you mentioned using the Flora series. I have found the EC to be pretty high if I follow the instructions on those nutes, so I often reduce it by about 25% and even more in the heat of summer. I use rain water, so I start with an EC of 0.
If there is anything you want me to look up in that book, I'm more than happy. I use it as a reference all the time. I'm using it as a textbook for my son, whose learning hydro, too. He's 13. My 9 year old will be next.
Yeah, $60 is steep. Of course, strawberries aren't cheap and they're really good for you, so it might pay for itself quickly if you happen to run into some extra cash. I like strawberries, but my wife really eats 'em up.
