well if your 22 days into flower than i guess next grow you can pick a mother or you can try and reveg what you have (if it is female) but imo that can be a big time investment and a PITA. I personally dont use a mother. I started 1st grow by seed and pull clones 1 week before switching to flower, that way I am constantly cloning every grow and dont have to play around with seeds. Also I dont have the extra room to keep vegging 1 or 2 plants to have as mothers.
