ph levels question

[SmokyLungs]

I know ph should be in the 6-7 range for healthy marijuana but every where i read it just states simply that but what exactly should be that ph the soil or the water runoff?

just your water / nutrient mix, ph to 6 to 7..
i'm not a believer in checking the ph of a substrate such as soil, and the only thing that testing the ph of the runoff is going to tell you is the ph of the run off, of course, imvho.

yeah, i'd not worry about ph'ing your soil.. most soil that you buy from the store already comes at a decent ph, unless you're buying say a soil that has a more acidic ph, but most will say high acidic soil right on the bag..
you could also add a bit of dolomite lime to pretty much any soil as a ph buffer as well..

and yeah, i think that checking and trying to keep the ph of the run off in check usually causes more issues than it solves.. k.i.s.s has always worked well for me..

How much of that lime do u add to the soil say for a 3 gal or 5?

1 TBSP/per gallon of soil, or 1/2 cup per cubic foot.

second on the dolomite lime, I still check the pH of my water to make sure it's not too far off but the lime will help a ton especially if you have something like peat moss in your mix
