You can't accurately ph tinted water when using one of those color-coded test kits. The tinting skews the results.

You might want to adjust your ingoing water to the high end of the ph range, (7.0 or so) and then add the nutrients. The nutrients will bring your ph down further, but ph should still be in the acceptable range. If you start to see the leaves curl ('the claw) or some yellowing...raise the water ph a tad more before adding the nutrients. The plants will let you know if that's ok. :thumbsup:

Was this what you were asking...?
