Hey Doc, So since we are on the subject of soil and ph, i noticed that roots doesnt add anything for a buffer which is fine for me since im making my own soil. My question is do i even need to add dolomite lime if im using the 6/5/3? i assume the calcium acts as a buffer itself but i dont know how much.

Good question, bro. It's been awhile since I went over that stuff.

The 6/5/3 is basically "Hillbilly High Brix." It was my attempt at getting mineralized soil and it worked pretty damn well. Because you're adding all that limestone, along with the gypsum and SRP, the pH is pretty stable right around 6.5 and there's not much you can do to change it one way or the other.

Adding Dolomite on top of that wouldn't help at all with pH, but it would decrease calcium uptake in the plant, making it much harder to achieve high brix. I don't recommend Dolomite for anything. Limestone is much better.
