why do you think some growers suggest a general ph of 6.0
 

Ron why do you think some growers suggest a general ph of 6.0. It has been critical for me to keep my ph at 6.5 to 6.8. Also all of the stress over nutrients, I use 5-11-26 and calcium nitrate equal parts @ 1.5 to 2.0 ec to grow everything. My plants produce very heavy and appear very healthy ? Is this the art of sales ? thanks Ed

I go buy what the commercial growing experts say. I figure they would know because they have a lot more to lose if they aren't.
