Yes .... really. I intentionally stress plants ..... "optimum growth" suggests providing conditions which do not lead to stress ..... i.e. no shortage of nutrients or water.

I'm not following you here given it is very unlikely you (or anyone else) has the data necessary to make this determination. I don't believe in blanket assumptions, nor do I believe that synthetics are generally necessary in your typical properly managed landscape .... particularly in non-turf areas. IMO, if you want to minimize inputs you need to find the breaking point of your landscape plants, then maintain your resources at a level that is slightly higher than that (i.e. one that doesn't impose too much stress on the plants).
