by far the best ph stuff that i have used is general hydroponics ph up and down, you dont have to wait for it to balance out at all, you add it stir it and check it thats it, and you use far far far less of it
mellogold Reviewed by mellogold on . What's the best way to adjust pH? Ok, I figured out the problem. Ph is off. I transplanted one plant into new soil because she was small enough to do so but this other one is too big and she has buds everywhere. Her Ph is in the range of 4.9-5.1. Way too low. Two months ago I had transplanted her into a 5 gallon bucket. The soil I was to put her in was at 8.4 pH. So the lady at the nursery recommended how much sulfur to add in the mix to lower her pH before I put her in new soil. I had mixed a Ph adjuster to her soil Rating: 5
