main stem snap

Hi! So this is my first autoflower grow and I'm currently 5 weeks into growth, the plant is still in its veg state, no sign of flowers yet! I gave them their regular (every two days) feeding before I went into work at 12 today and all of them looked amazing and healthy! I came back 5 hours later...

pushed a bt too hard on my lady if you look at the photos, i know plants self repair but this is on a bit larger scale will she fix or should i just chop n clone. i tied it back up with some hemp rope fingers crossed would be a shame to lose that branch
