I would not worry about flushing them, that is mostly a myth. Just give water at normal amounts and they should be fine.
I would guess you have anywhere from 2-4 weeks left in this. probably close to the 2 mark though.
did you top these plants at all? I know diary says LST and no HST they just seem a bit small for their age and wondering if some sort of high level stress occurred, Might be best to try and not do that again in tie future might be able to get more out of this strain.
Good Luck!
