Hello,
I don't think you're quite ready for bloom yet, another couple weeks to go.
That bright green growth can be very common in this vegetative phase, and as long as it continues to grow out into healthy green color don't worry. The only possible thing i can think of that would cause that bright new growth is an iron deficiency which is pretty uncommon if your using tap water, good soil, and have a reasonable ph.
Let it keep growing and watch for any worsening situation and bloom will start in a couple weeks if its an auto, or once the light hours reduceif its photoperiod plants. 👍
Happy growing.
