JavaMon...actually you are the one thats wrong buddie..... you should do some reading on ORGANIC growing before trying to say I'm wrong.... Understanding the soil food web is vital to organic growing and I suggest you do a little reading in this area before commenting and trying to pass off incorrect information... I own a Hanna PHep digital meter and my feedings are 4PH....at the time there added to the soil... I have not once had any nutrient lockup issues, no leaf discoloration and my soil sits comfortably at 6.7ph....
you should do a little research in Organic growing Java...you will learn a lot about plant mechanics and understand all types of grows better. You would be correct if I was using salt based fertz, but oraganics, you should NEVER PH adjust..
Also If you are using city water, your PPM count probably is at least 200ppm...and using ph adjuster's you are adding another couple hundred PPM to bring your nutrient solution within range....Higher PPM before nutrients = less nutrients available to plants and more unknown variables in your feedings....So I would highly suggest not using city water, and also looking into organics....
