I started at 2 ppm water but oh was high I added ph buffer powder to get it to 5.8 but now my ppm 760. 1 did the buffer raise ppm 2. Is the ro water still basically 2 ppm or is now hard water

I know ro is stripped of minerals. My purpose for plain ro water is for sprouting seed. I just want to lower ph from 7 to 5.8. But when I added ph powder it raise ppm now I need to know will the water still act as if it’s jusg plain ro water or is it now considered hard water like coming out of faucet or somebody that nature

RO water doesn't give a reliable pH reading since there is nothing in it. Consider it 7.0 if it's super low PPM.

basically pH is moot until you start feeding, ie the plant has its first multi bladed leaves and stops using it's seed reserves.

700 ppm doesn't mean it's hard water.
What does hard water contain?
  • Calcium
  • Magnesium
  • Trace amounts of other minerals
It’s a natural result of minerals like calcium and magnesium accumulating during the water cycle, and it can happen with well water and even city water. The more calcium and magnesium dissolved in the water, the harder the water becomes.

He did give you an answer. You don't have to worry about PH when it comes to seedlings

yes adding anything to water raises the PPM. A bad pH buffer will raise it way more than a good one.

GH makes a good liquid buffer set for smaller setups, for larger setups the Advanced pH buffers are more concentrated so will require much less.

Also, you pH after adding nutrients.

Never water with plain RO.

Do you only add epsom salt most the time? I see people saying to add cal-mag for under LEDs do you add epsom salt with the cal mag? What ppm do you shoot for? I'm vegging under t5's and flowering under led's and just switched to RO water.

What pH powder are you using?
