Flowcharts for identifying nutrient deficiency

I found these in a PDF from Montana State University. All credit goes to them & the source can be found here: http://landresources.montana.edu/NM/Modules/Module9.pdf
 
 
Another good resource with better descriptions can be found here: http://ag.arizona.edu/pubs/garden/mg/damage/key.html
 
 
 
 
Some nutrients are mobile & the plant can send them from old leaves to the new ones. Deficiencies in this category tend to show up in the oldest leaves first as the plant redirects the nutrients to the new growth:

Other nutrients are not mobile within the plant & tend to show up as problems in the new growth first:
