He had more to say too, Rick. I can't quote him exactly anymore, but he explained it something like this: At any given instant, there are processes going on within the entire plant. And those processes are continual so at any given instant or snapshot (if one could take one) there are some virgin nutrients, some in process nutrients and consumed nutrients in the form of the plant and by products. So at any given time if you had a snapshot profile, you could see each nutrient in some state of process. He said that process rate is respondant to temperature; when it's cools, it slows down gradually, when its warms, it speeds up gradually. But, when it gets hot, plants go into a protective mode as in survival mode and things really slow down and that it's those partially processed and unprocessed nutrients within the plant that can cause problems, mainly those that have an affinity for water or those that are tieing up water at some partial state of process and then hold it there until normal process rates can resume. And, of all the nutrtients, Nitrogen was the one nutrient most to blame because it ties up so much water or tightly associated with so much water within the plant (processes) that wilting and eventual burning result: hence it's called Nitrogen burn. He went on to say that if it turned cool again, most all my plants would resume their processes and 'perk back up' to normal, but if the heat lasted a few more days many would die because the high Nitrogen/Water content in the roots (pointing at the bleeding heart roots) would cause them to rot (why?) Now, this was his explaination put forth in my words. I bought it because I had great trust of his vast, hands on, field knowledge. He seemed to know everything there was to know about plants--and confident. His explanation may or may not be totally accurate today tho. His age was about 70 at the time. Working back, that would mean his education was late 1940s/early50s timeframe. Sometimes, I question an education going that far back. I never even thought about running NPK test back then--what a shame!
