so with only a few drops of PH down I am now at 5.6
I will take a test in an hour and see if it is stable there.

Other than 5.8 what else pertains to PH levels and adjustment.

Example, are nutrients added to water then the solution is tested and PH down added accordingly? Or do you adjust the water first and then add nutes?
