cheoking runoff is standard procedure for any system.
plants do not use minerals evenly. not overwatering means every mineral not used is buying up interfering with proper uptake of the rest.
runoff is 5p easy not 4o check. it takes no effort and allows 5ou to notice issues before you see it In the leaf. once you see s leaf issue it is already to late . now you are just putting on bandaid. it better to avoid issues with proper maintenance.
