Yer i reckon this is the reason for the pH and what you should address not the actual pH. All info in this thread leads to this fact i hope, pH is a hard subject to debate but easy to just feed right and use runoff to see when to feed next.
In hydro (although apparently nothing to do with soil) we see that as time goes on the nutrient mixs ppm drops and pH rises. To me this is the same as soil, we add fertilizer (which at their most fundamental are salts Calcium Nitrate, Sodium Nitrate, etc etc) and our plant uptakes these ferts/salts so our ppm in runoff will drop i.e. runoff 1400 after feed, two weeks later 800ppm/ pH 6.2 after feed two weeks later 6.3/6.4.
I guess its hard to read in soil but were basically applying the same principles with the soil acting like our hydro resovoir.
Someone shoot me down if im going to far but my understanding is such,
As in hydro a plant might uptake more of one nutrient leaving an extra amount of that particualr nutrient behind in the soil and eventually leading to a toxicity to which point we need to flush or in hydro we would do a res change (as long as not flood to drain but we get the point).
People say hydro aint soil but i see little differences at the base levels and hydro explains it better sometimes with pH and nutrients, soil just makes us think of loads of soil like variables and we cant see through the mud for the water.
People have a sig like all this is make believe and i dont partake in illegal things, possibly all my posts should carry the same sig. Peace
