I dont really know how you can say this. If your plant is showing issues and you dont know that the soil you are using has a low PH how will you solve the problem. If your showing a deficiency in Ca , P or K and you throw more at it not knowing your roots are locked out, all you will do is make the problem worse.
Sometimes i find that people just want to go against what is said on this board. I had this issue, and adding dolomite lime to my soil helped balance the PH.
Before checking my run off, i had no clue my ph coming out was 5.2 , so throwing 6.5 ph water at it did zero and the problem continued until i added dolimite lime to the soil to raise the PH. Once i did i noted that PH runoff was around 6.2 and now i have happy plants.
