Why is new growth purple at only 3 weeks old?

Hello Sometimes that red or pink tinged growth can symbolize over watering and root bound...which could be possible, but more in the way of adjusting to being transplanted, sometimes the new environment of a big pot that's very moist and the roots re-situating can bring funny symptoms. I think this color is just temporary though, let her fill in and relax and i expect the leaves will grow out to a green color over the next week. Happy growing. ✌️
