Pineapple chunk advice

[saltybluegrass]

soil grow 3 gal pot - she almost makes me think she’s an auto as short as she is - she’s been under 24hr light since birth along with her 2 auto friends in the tent.
Does this need repotting? how’s she look growth wise ?
purple pic was 1 1/2 weeks ago -white pic is today- i poured 2200 ppm on her but flushed it next watering and got minor burn inside

She looks ok. I think it would be happier on 18/6 if she's a photo vegging. Looks like the pot is good for now. I've read PC is a odd growing strain, but a good one smoke wise
