Well I ran 3 gal of RO water through it so I think thats a pretty good flush. So you think I should back off the amount of nutes I am feeding her? Is that what you are saying?

One thing I have checked since the flush is the PH of the feeds I have been giving her. My tap runs about 4 PH. I basically fill a half gal up with tap water then add probably a couple tbs of canna nutes let it set for a few days then pour it in. I could be over feeding. Another thing is when I add the nutes to the tap water it lowers the Ph to about 2.7. So I have basically been feeding this girl a low ph but the promix bx has a built in buffer of lime but I think watering it with a low ph as I have has deminished the buffer. So should I be pouring my feeds with my Ph in the 6.3 to 6.8 range and if so what is recommended to add to the feeds to raise it. Currently I dont have any Ph up. When I did hydro I always had a high ph issue so I got some Sulfuric Acid to keep it in check just a drop or two to the resevoir worked perfectly.

Is there an issue with the Dolomite sounds like you dont like it. Unfortunately I did not take note of the EC/PPM my bad as I have always been used to just keeping the Ph in the prime zone on my soilless grows.
GodBud Reviewed by GodBud on . Need Guidance on Ph issue Quoted from Site Adjusting pH Of Marijuana Grown In Soil A good way to stabilize soil is to use dolomite lime (calcium-magnesium carbonate). Dolomitic lime acts slowly and continuously, so soil will remain pH stable for a few months. Using fine size dolomite lime is important, coarser grades can take a year or longer to work. You can find fine size dolomite lime at any well stocked garden supply center. Dolomite lime has been used by gardeners as a pH stabilizer for many years. It Rating: 5
