I made my own huge budget organic super soil (about 4000L) with a few amendments like gypsum, rock phosphate, dolomite lime, kelp- and bone meal, also long release fertiliser pellets with all the necessary macro- and micro nutrients as well as compost. I had it cooking for about two months when I did my first runoff test and I got a value over 3000ppms with RO water ph to 6.5. A few weeks later it went up to almost 4500ppms. Can I flush the soil a couple of times to lower the ppms or should I add soil to increase volume and in turn reduce the ppms?
