Still not equaling a dollar so here’s my 2 cents....flushing ,as I have read, is to flood the soil with large amounts of plain water to wash away any buildup of nutrients, salt, or chemically combined elements from residual remains or excesses. It’s this process that nearly eliminates those compounds from the soil that the plants roots extract their “food†from. In a living plant, the feeding process is always in a state of flux where it is drawing nutes up from the surrounding root.
consider an escalator in a building...one usually going up, the other usually going down. These are xylem and Phloem in plant terms, the up and down veins thru the plants. If there a people on it (nutrients etc.) they make it to the top and converted to food etc.. However ....when No one is on the escalator it still runs but all of the people are gone.
with the flooding, the compounds are flushed away from the soil, with plain water feed, the plant thrives on moisture but....lacking nutrients, it utilizes stored Compounds in it leaves and they begin to reduce levels of built up elements within the plant until. A) harvest or B) nutrients are re-stored to the mix
$ .98 cents + $ .02 cents = $1.00. Bingo 😉
