Since I know WW is an experienced soil grower that know's his shit, I think that if I were a newbie...I'd be more inclined to listen to his insights, rather than listen to "a hydro grower stuck in soil". I doubt he is referring to every single "yellow leaf" post, but more likely than not, he's referring to a growing percentage of overfert issues. Perhaps instead of arguing his insight, you take his insight to heart when "fixing" other gardeners plant problems. Quantity of nutes needed is determined by soil used, water ph, proper organics in the soil. The nutrients should be used kinda like ammendments. (sparingly at most) Would you defend the addition of Miracle Grow All Purpose, when in Miracle Grow 6 month...just because the label says to feed every two weeks...or would you instinctively know not to over-do the liquid ferts while in THAT soil...?

But I am of the same opinion about CanCom. Since this has transitioned over to a teenage recreational cannabis site, the quality of the posts and responders has fallen-off dramitically.
