Fimming success?

it looks like you did a bit NOT enough, aka mission to have multiple tops - failed, BUT : you main stem will slow down to develop, try to tuck leaves under smaller branches exposing them to better light. Thats how i found my way to train girls, now i just twist most running stems between fingers like straw, that slows them down, while others catch up, helps to make even canopy. i called it antiFIM at first, later stopped even cutting. for successful fim you have to leave like 30% max, looks like you was in 60-70 by leaf development ..

How ago did you fim it i generally take 70-80% of the new growth and yiu should be able to tell if it has worked as the plant should get a lot bushyer hope this helps
