@Worl' Boss heres what I’ve learned over the last 12 years.
when growing FULL RECIRCULATING HYDRO you monitor your reservoir for changes in ppm/EC and pH.
I’ve used soil once.
Been predominantly coco for 12 years with a stint doing full recirc hydro.
during the final few weeks you can track your reservoir changes each day.
As the plants begin to ripen their demand on nutrients diminishes. Meaning they take up more water than nutrients during the final few weeks.
this manifests itself in rising nutrient strength returning back to your reservoir.
You will be able to find an equilibrium during the last few weeks where your nutrient strength comes back almost the same that it went out.
my theory based on this is that plants are using less and less nutrients towards the end.
Personally I never use plain water in my grows!
However if I was using soil, the soil holds on to nutrients and releases them back to the plant so it would stand to reason that “leaching” during the final few weeks of a soil grow would not be as detrimental to a plant as it would to use plain water with a hydro grow.
However with this in mind that’s on the understanding that your plant is healthy and green when you begin to do this “leaching”.
I’m a NON FLUSHER though but by the time my coco plants are finished they are receiving approx the same nutrient strength that my seedlings were receiving.
