I've recently had a water test done by the Soil & Plant Nutrient Lab, but they are unable to provide recommended optimums for the various levels.
I've tried searching here and on google but come up basically empty. Was hoping to find a list of all of these with the recommended ranges.
One thing I have learned was that phosphorous is too low, especially for cukes & toms... should be in the range of 20 - 40, not 0.2.
Have also heard that magnesium deficiency can be a problem in AP, but what is too low?
I would greatly appreciate any comments or reference links to help me interpret these results.
p.s. I've found lots of resources that say look at the leaves, but it also appears to be a lot of overlap or combination of symptoms that look similar. So I did the water test to be certain.
