do i need to transplant it?

hey whats up you groovy people?
this girl here is about 8 weeks old and its her 2nd week in flower still not much growth just some minor strech and a few hairs here and there
is it safe/necessary to transplant it or i dont need to do that?

I hate being this guy, but your plant looks seriously underdeveloped. Especially for 6 potential weeks of vegetative growth. For a plant that small, that size pot should be fine. Is it an AUTO strain or photoperiod?

dont consider transplanting while in flower until you have no more gardening questions.
your pot size is fine for the whole cycle. your plant is too immature to be flowered imo.
I would consider putting under 24 hour light for vegging until the plant shows some sexual maturity, maybe a few more leaves.
plants dont like lighters either, so get that out of there

add more light asap............or you will be harvesting a couple of grams of smoke and won't be worth your time invested.

good luck grower
