I have a question in regards to pH levels when growing in soil using super soil(foxfarm).This is my first grow,I will normally be doing hydro but I got clones from my buddy and they already in soil.I am currently in the flowering stage,I am using 600 watt HPS(not sure if thats needed to know).I am trying to figure out what the pH of the water to feed should be.Ive read so much different stuff on the internet that I'm not sure,one says don't even bother checking it,another says 5.5-6.0,then my buddy told me not to worry about adding bites to water just use cal-mag and molasses.The strain is purple kush.....help
