i only vegged mine for 10 days before switching to 12/12...

but if you want a zip from each plant and you have the patience, then i guess give her another 2 weeks...

ont worry about size tho m8, they will grow a lot after you switch them... The first 2 weeks of 12/12 is gonna be one big spurt and then it'll slow down alittle bit...

i cant wait to see what your flowers look like.
