get a ph water test kit.after you add your nutes then test the solution.
if the water is aqua green to yellowish you dont gotta add nothing.
if the solution is light blue or blue then you must lower the ph.

when you lower the ph make the ph so when you do the test the water is aqua green shade to yellowish,not orange or red,add the ph in increments so you dont lower it to much cause you dont wanna add ph up if you dont have to.

if you lower it to a yellowish color you wont have to add more down as soon.
if you lower it to a aqua green you will have to re -lower it in like 3-5 days because the ph will climb as time goes by.


if you use well water you must use a reverse osmosis machine.

PH ACTING STRANGE DOES ANYONE KNOW WHY MY PH IN MY NFT SYSTEM IS GOING DOWN AND NOT UP, IT HAS ALLWAYS GONE UP FOR THE LAST 8 YEARS OR SO, BUT THIS LAST SIX MONTHS OVER 3 GROWS HAS BEEN GOING DOWN. I DO CLEAN MY SYSTEM AND THE PLANTS ARE GROWING AND LOOK FINE. BUT I READ IF ITS GOING DOWN AND NOT UP, THERE IS A PROBLEM, I HAVE CHANGED NUTRIENTS ON THIS GROW BUT STILL THE SAME AND THE WATER IN THE TAP IS STILL AT 7PH SO I DONT THINK THAT THE WATER IS FUNNY. ITS REALLY WEIRD. Rating: 5
