You would be absolutely wrong on that therorey. The ph flux due to the ppm to volume ratio this flux is what you cahrt to know your plants needs and current uptake. A fluxing ph will cause damage and hurt your plants if left unchecked. The standard and scientifically proven ph of the 5.5 (more for aero) to the accepted 5.8(general hydroponics such as flood and drain) allows maximum absorbtion of the nutrients and water. Now as the water level falls if your plant is in perfect harmony the ph will stay stable. If the water falls and the ph jumps then the plant is drinking more and eating less so you can cut back the ppm levels a bit. If the water doesnt drop but ppm drops then the plants are hungry and you can bump up thier nute ppm. As you go you will learn about ph and ppm and direct relation to your plants needs and health. A high ph or extreme low can cause nutrient salt build up and nutrient lock out which will show in your plants dramatically.Ive grown hydro for about 14 years and aero about 4 now with several hundred grows and have dialed in the ph pretty well now and can speak from years of expirence the need for correct stablized ph levels which is why most nutes have a ph buffer added to maintain ph consistency.
possibly the most informative post i've had to any question i've had. siomeone give this man some rep, cause i don't know how.
