I will be switching from our local lab to Nova Crop Control in the Netherlands. They are testing the plant sap instead of the tissue. You send in two samples, one of the new growth and one of the older plant. From the results you will be able to tell if the plant is cannibalizing itself from lack of nutrient uptake/availability. They say that by doing a sap test, they can predict a deficiency up to 1 week sooner than traditional testing. I really like how the results are displayed. Joan speaks very good english.
