Never used the Recharge. With Natures Living Soil I did the "living soil" mixture per the instructions and it works great. I started the "living soil" about 2 weeks prior to planting to get the soil microbial life going. Water and ococcasional molasses for feeding the microbial life for "living soil" if you ever go that route. Ive also added kelp, worm castings and fish emulsion in a tea with great explosive results with this.
Your plan for a Super Soil should work just fine with adding water only (water that has not been stripped). You should not need anything else if done per instructions and if you do for some reason run into a deficiency you can simply make a tea with it and that should fix any deficiency that may come up.
Also, i wouldnt transplant right before flip, transplant and let the roots establish for about 2 weeks and then flip. You dont want the plant in any sort of shock when going to flower. IMO
You can re-use your old soil afterwords by just redoing the mix with NLS agian.
Hope this helps some.
