m0useanswered grow question 3 years ago u can top/fim as much as you want on a photo. sorta, it will set its life back a lot before it mature to flower but its possible.
Granted you only want to do that max maybe 3-7 times. other wise it will be so bushy no air or light can get though. and then it will suck up all the nutrients and water out of the container faster then you can add it in.
Good Luck.
