There you go again, talking about stuff which does not matter. Your issue is you do not read what goes contrary to what you "Know." This is why I can teach a newbie how to grow better cannabis than you do. Their cup is empty. shrug
Nutrient line does not matter, as long as it's properly balanced for the cannabis plant AND is pharmaceutical grade. Why? Go look up phytoremediation and couple that with "no one can tell the difference when I use r/o."
I don't get sucked into useless conversations, I only do my best to open awareness.
