Good point, Urban.
This thread just reminded me of a really lame science project my daughter did when she was about 9 in the mid-1990s. It was about the time that Miracle Gro became the leading fertilizer on the market and folks where I lived seemed to be indiscriminately drenching everything with it. She planted three sets of radishes in sterile potting soil, fertilizing one set with full-strength MG, one set with 1/2-strength, one set without. I can't remember the point of the project unless it was to prove my own opinion at the time that MG was formulated too strong
Looking back, I realize there were some fundamental problems with that whole setup
