Hey there, my educated guess would be potassium K deficiency.
It’s common that Autos can’t take nutrients the same as photos, I’ve found some strains to be heavily k dependant during stretch and others more Sativa dominant to not like much K at all during stretch but more closer to the end.
But yea, the Lime colour leaves as she’s stretching is a first clue for me, week 7 is the tips, looks like nutrient “burn” but it’s actually a deficiency of K, then by week 8 you can see the edges of the leaves are effected.
It’s a very common def often mistaken and I see it all the time. I don’t comment though... I’m growing this girl again also. Last time was in a 1L pot and she was some of the tastiest auto I’ve grown, right?!
Awesome job plant looks a beast just pity about the leaves as she was looking perfect. Never The less your buds will be dank!!
