Now I don't grow in soil, but the recharge should be what saves you. You want to make the mediums microbial life strive again so you can get that nutrient exchange to the root zone, your soil should have some food in there and the recharge will help mine it. Now as for water, you would need to check the amount of sodium in your water so ppm, anything over 250 will just fry the plant with salt. 10 and below is good. you can get some spring water from the store just avoid the RO. I used RO and I had all the deficiencies show up within a week. I would look into things like dolomite lime for calcium but can make the medium a bit to acidic to treat with care. Bat guano and some worm castings with an ayirstone for 24hrs will make a nice tea, you can add a bit of that living soil in there too in a a mesh bag fo a bit of NPK. Teas and recharge should be like additives to make her happy, the soil is the real meal.
