Just like a Fat girl who stuffs her face with Pizza Plants get used to eating a lot. Take away a Fat Girls Pizza and she is going to react, so are plants. When force growing you must slowly remove the fertilizer just like you would throw the Fat Girl into a fat camp or rehab.
If you are talking the Home installs in the Irrigation system, Stay away from it big time IMHO.
My Bad. Because I used Fertigation for force growing I just replied as if you were force growing also. But my answer about Home lawn Fertigation is still the same, It is not all that successful. In containers plants won't show a big difference in growth or color like a lawn will. Most all irrigation system will have wet and dry spots and those spots will have different growth and color. also I believe the Granola Fruits and Nuts will find Fertigation Politically incorrect. You are constantly releasing soluble Chemicals in water into the environment.
