yeah itll stretch in the upcoming weeks you can also pull the lights up to increase internodal space a little bit more. then lower them after 2 weeks to let those flowers fill up nicely. with photos there is a technique of signifcantly reducing the dli for the first 1-2 weeks of flowering then gradually increasing it moving through the peak of flowering (week 4-5) then slowly decreasing again as you get closer to maturation. the idea is increasing the stretch during transition which gives good space between budsites. then increasing dli and intensity so the plant can fill that long internodes with juicy fat buds and then lowering intensity at the end to preserve quality of the buds. this should work similarly with autos as well as long as plant is vigorous and healthy.

Looks like she just started flowering so you can expect some rapid growth over the next 2 weeks. Autoflowers are usually shorter. Good luck
