Did anyone have any more thoughts on whether or not Canna were diluting their A+B? Anyone with an EC pen check it out?
Don't know if I have old stock but I bought my most recent lot about 6 months ago, my Canna feed guide (created using their calculator in 2009) still seems acurate in terms of expected EC by dose (although it's a bit high all over imho) in other words, I'm not seeing any difference in EC...
Could there be other reasons for it not performing as well as it has in the past? Basic mineral profile any different?
