Water PH Question

Is there a reason why in a day my ph level goes from 5.50 to 5.98 or around 6.0...i gotta keep putting ph down...and im wondering if i should worry about using to much?

or just keep adding to maintain my ph levels...

growing a fresh sprouter of Kush at the moment...

your plants are eating the acidic nutrients ... so the ph goes up. You are replacing the acidic nutrients with an acidic ph down ... If you add more nutrients at that point the ph will go further down. So the proper cycle would be feed, monitor ph and replace nutrients with ph down as needed, change water, restart.

just make sure you flush ou the salts and change the resivor(s) regulary one a week is best
