I thought that a PH of 6 to 7 in soil was ideal
lmao.. dag nabbit pops!! now you got me trippin lol im gonna be reasearchin now the rest of the day. I guess it don't really matter as my dry soil ph is 7 so when I use AN ph perfect nutes it goes down to 5.7. and goes up as it dries, usually over a 3 day period.... so.. all nutes get absorbed anyways.isnt that right? I don't know its still interesting why theres so many different soil charts.
weird. heres the 1 I use. seems to be working fine for me so I use the 1 I been using. thanks. http://www.420magazine.com/forums/indoor-soil-cultivation/114733-ph-nutrient-uptake-charts.html
