A little knowlege goes a very long way when it comes to nutrients. Fisr thing to remember is that all the salts are the same, so why pay so much for them? Jacks is a powder nute, that costs literally pennies per res change. Use it along with Calcium nitrate, a basic fertilizer salt- even cheaper- and you're providing similar or better quality nutes to your girls for 5% of the cost. That leaves a lot of money for things like a good pH meter and EC pen, items you will always need. Even if AN says its nutes are 'pH perfect', don't believe it for a second, as everyone's water is different!
The reason why so many people hate AN so much is because they make their money preying on people with little or no knowlege of what nutrients are and how to use them properly. What I'm trying to say is that for the money you'll spend on AN nutes, you can get equipment, inexpensive ferts AND an education that will get you ever so much further ahead than trying to use stunningly expensive nutes as a crutch.
