The plant always knows how old it is, check with your breeder to identify how old the mothers were. They will try to flower, but also clones are highly susceptible to Flippin to flower, understand what light cycle the breeder had the clones at and mirroring that cycle.
I don't like to reveg anything, you make a Zombie, and I promise you will have Bananas at least, pollin sacks all over the place.
Just flip to flower and get better clones, more reliable clones I mean, not "better" just better managed on the propagation side.
This isn't your fault. Keep moving along and don't waste time revegging those. Just my 2 pennies
