2nd Top puzzle

Ok so I topped my plant a Mekong High fem as per normal at the 4th Internode etc. Hunky dory. But now the two new branches which are about 2-3 weeks old and long have branches coming off them BUT they are at different heights if you know what I mean. Not the same as first top where branch interrnodes are all at same height. So where do you top these branches cos they dont have classic internodes.:eek:
