Ideally, your water, with nutrient added, is pH'd prior to being given to your toe-mah-toes.

Dolomite is fine...for keeping the pH closer to 7. Too close in my opinion anymore. Gauging how much to add to soil, and where to disperse it in the soil...unless done just right...the soil around and below (due to gravity) the lime will continually buffer the pH back toward 7.

ie...while you're pouring pH'd @ 6.2 water....soon as it hits the lime, it will have either a gradual raise...or jump right into being buffered at 7.

So while dolomite and other limes are good for auto-maintain a buffer zone that plants can live in...it will also make it difficult to create the buffer zone that plants thrive in.

How do you know the pH is dropping below 6?
slowthestone Reviewed by slowthestone on . PH PROBS. from my understanding in soil your spose to bring the PH to around 6.4 after nutes are added, is this true? Also do you reccomend using dolimite lime in fox farm ocean forest soil? If so, how much? My tomatos are dying and I think it's a PH problem. In the beginning I never adjusted the PH after nutes, just before. I find out that after nutes are added it drops below 6, can this be cured with proper phing now, or am I fucked? Help Help Rating: 5
