ph down on sensi grow ph perfect

I tried to ph down on the advance nutrients sensi grow part a and b, but seems it wont go down even tho i put a few drop of ph down in it.. stays at 6 and 6.5 around there.. i know they said we dont need to ph but seems a bit high for mine dwc.. just want to know if anyone tried to ph down to like 5.5 or something close..

You're gonna need more than just a few drops. It takes me about 20ml of ph down to bring my 27 gal res' from 7.0 to 5.8 (5.8 is optimal for low pressure aero, which I run). Hope this helps and have a good one!

As AK said, you need a lot more than a couple drops. I run a 5 gal bucket, i mostly work with a conversion of .25-.5 PH per ML(if not more or less) depending on nute strength.

cool.. thought i was adding too much

Are you shaking everything enough? There's probably something else going on if you are having ph problems in dwc with advanced.
I also know from experience that mixing sensi grow at half strength will cause ph problems. It's because it has ph buffers in it and if only half of the buffers are there it's not going to adjust properly or last. Use the recommended amounts
