Keep 3 nodes on all the mains you are keeping to develope into cola's and take everything below that off, its still in veg it will take a couple days to recover from that but it wont hurt any potential yeild quite yet and will have plenty of time to grow from there before flower, if its only 5 inches tall then you could veg for a few more weeks if you want to and that many colas i would and lightly prune one more time just before you flip the lights and let her go from there, looks really good though and dont be to worried about trimming that little ladie, she will grow those mains from there and have some good growth energy going into the flip if you trim and let it come back and give her a light trim before the flip
