Yes, I did draw this a few months ago. It is meant as a rough guide to what happens when all nutrients are kept at the same concentration (non limiting) and then one is decreased to the point of deficiency. This diagram assumes good CO2, O2, light, etc... are all there except for the indicated nutrient which results in the deficiency shown. I made it by combing literature on terrestrial plants, aquatic plant observations from hobbyists, and personal experience.
Reabsorbed means the plant either destroys certain cells (or structures inside cells) and absorbs the nutrients and components that make up those cells back into the plant for use in new growth.
