HEY STICKY !!! why ? why ? why?

Iv been growing hydro for minute never had a problem or a mite ..i run two aquamists in my main room and those grow themselves (so boredom snuck in) an i built a system using external rez such as in the aquatop but instead of jets im using 1 circulating sprinkler (two rezs) one holds plants one holds water and nutes bottom rez contains pump which send water to top rez sprinker sprays roots an returns via drain hose to bottom rez..... MY QUESTION ????
I HAVE ONYY HAD TO ADJUST THE PH WHEN I CHANGE WATER OTHER THAN THAT the highest has been 6.3 the lowest 5.8 (steady the entire grow) im flushing right now i figured with just water i would finally see ph fluctuate NOPE STILL 6.3 or 5.8 I EVEN BOUGHT A NEW PH PEN TO MAKE SURE THE GANJA WASNT GETTING ME ...THIS IS a wonderful thing .. BUT I DONT KNOW WHY??? Is it because the water the sits in a seperate rez? is it the extra oxygen from the sprinkler an water returning to the bottom rez ??? i just dont know AND I WOULD LIKE TO HEAR some solid theories???or facts

It sounds like a dream, When you get it nailed down to just why, you better bottle it:thumbsup: cause you are sitting on a gold mine.:D

what kind of water, filtered,or RO,what is the EC, what kind of nuits,what strain. you need to give with some answers here.

the nutes were gh powder.. no filtered water community tap ... i started @ 300ppms an bumped it up a 100 every week until i reached a cruising altitude of 1000ppms but only had to adjust ph when i did a rez change IT NEVER ROSE ABOVE 6.3 NEVER FELL BELOW 5.8 and i wish i had some way to explain it i would like to sound cool too...:rasta:
