Starting soil values

pH is definitely a problem. Organic often reads much higher in PPM than what matters -- int his specific case, not everything can enter the plant, so the water that diffuses into the plant will have a lower ppm than what is in the soil -- this is not the case with "hydro" nutes that are 100% soluble and 100% plant-ready, therefore go into the plant fully and immediately as diffusion across semi permiable membrans of the roots occurs. 4.8 pH will lock out nutrients. it doesn't matter what kind of fertilizer you are using. now, soil pH readings are suspect to start. so that is also a consideration. any experience with this soil before and didn't measure these things? sometimes ingorance is bliss. running a bunch of ph-adjusted water through it will only waste your efforts of creating the soil - a lot of nutes will just go down the drain and never be used. so in future maybe find some amendments that help correct his low pH. water and let it simmer a bit to even out. Like adding garden lime i belive raises pH. This will provide a good amount of calcium too. possibly have to adjust anything else that adds Ca, if previous ratio/concentration of nutes was proper to start. mix some in, get it wet so it dissolves a bit, and it should cause pH to rise. can test with small sample of soil... work out ratio you want to add to large volume without ruining it. if you make amistake can just toss out teh small tester sample you used. so in regard to the ppm of the nutes.. it depends on many factors that are not given here. as far as the pH, if true, you definitely want to adjust that one way or another. 99% certain.
