Give up on seeds?

For what it’s worth, and a shout out to @Spiney_norman and @Randy_Marsh (for advise on a separate post of mine); I soaked (4) Blueberry Fem and (3) Northern Lights AF for days (3 or 4) without anything more than a tiny tail (see pic). I decided to plant them all (1 NL died), which will bring me to my question below.

Believing none of these would sprout, 'cause I’m a newbie (1st grow) and have no experience, I planted these two or three in the same Jiffy-pot.

The question: if/how/when can I separate these into individual seedling pots?
Please advise.
