For fuck sakes people. Plant some new seeds in their own pots, problem fucking solved. You wasted 20 days because you weren't thinking clearly, probably high or something..congratulations. Now...learn from your mistake and get on with it.
If it were me, I would just pop the soil out, and wash all the dirt off the roots. Gently peel apart and transplant into either new soil and a new pot or say screw it and go Hydro.
I also cut roots, I mean I CUT them off, like 1/2 the roots off my mother plants in one good cut. This makes their growth slow down for a couple weeks, but in no way "harms" them. If I did not do this they would outgrow the whole DWC setup with root mass. It grows back incredibly fast.
