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.
