both in the same container was a bad choice but that can't be fixed now. transplant the whole thing into a bigger grow container. flood your container with 2x more water then you have soil so 2 gallons of water for a 1 gallon pot 4 gallons of water if you have a 2 gallon pot ect ect. place the stem between your finger turn it up side down and the whole thing will come out in the shape of the container much like spam then just place i na bigger container with soil alread i nthe bottom and fill around the edges and rewater and feed with 1/4 nutes because you basicly just flushed your plant and need to re introduce nutes. then just wait a few days befor you water again and you should be good to go
