To be honest, I was being a little sarcastic. Sorry guys.
I was very pleased with pulling nearly 4 zips from those 2 gals, especially since they are autos, grown in a cupboard, under CFL with cheap MG products and especially since it was my very first grow. I have neither the experience or knowledge to say whether someone should PH their soil grown plants, but personally, I'm not going to fool with it unless something drastically goes wrong with my plants and I've eliminated everything else. All I do is fill a gallon milk jug with water from my tap and set it aside in the corner of my kitchen for a day before adding it to my plants.
