Chris, I think were surfing on the same wave. I may be interpeting the
chart on p.47 eskewed but i thought that those numbers were guidelines in
ppm. to stay balanced. between CEC- K-Mag-Ca If this is correct then i
felt like this was it the recipe guideline give or take. I decided to see
if there was a corrolation between those that were sucessful and how
closely they fell into the chart. Thus the questionaire. Some that are 1-2
year growers that are in the ballpark of those guidelines hit in the 800.
Do think there something to this?? Of course this is only one of the
environmental factors.....MB
