Thank you. I am on a well so no city water. My water is 8.2 ph 125 ppm and between 40-80 ppm alkalinity. I’m thinking I don’t need to use ph down. Would you agree?

This is the way I look at it...if your plants look healthy, and aren’t showing signs of pH issues, then it’s really not worth worrying about. I pHd the water (but never my nutrient feeds) for the first grow I did in ProMix HP and I had good results. During that grow, another grower told me he found he never had to worrying about pHing his water with ProMix HP since he started preamending it with some garden lime, and adding more in at the flip to flower. I followed his advice for the next few grows, stopped PHing my water, and I had no pH issues.

Its not my opinion, many dont ph it and have worse water great plants.

But you keep on telling everyone to ph a product with lime in and how it will solve their plant problems!

Did you even read what I wrote? Adding the garden lime doesn’t pH the soil. ProMix HP already has some in it...adding it just prolongs the buffering capacity of it. I never said pHing the water or the soil would solve their plant problems. In fact, I said there’s no point in screwing with the pH unless the plants are showing signs of issues caused by the pH being off. I’m not pHing my water so I’m not sure why you think I’m pushing them to do so.

There is about four different opinions, who cares about yours. Its not a site where one overall answer exists that everyone can work of.

Might as well start flushing again.
