Stopper pousse en hauteur

is it in flower? got pics? pics would really be helpful

Along with what @Chow_13 said, I'll add LST which I'm thinking would be preferable given that your plant is in flower.... just bend the more pliable a little bit - or pull the whole plant over a little bit.... you can see what i had to do to my Tangerine Dream when faced with the same problem! Good luck!

You cant stop it from growing up, But you can slow it down or even bend it so it is lower. HST - high stress training. - "Topping" will slow down the growth as it will have to recover as it starts growing out the lower nodes. - "Supercropping" bending the branch so it has a sharp bend in it to lower the canopy. LST - low stress training -Bending over the branch so it is lower but keeps its stem structure intact. - SCROG putting a new above the plant and as it grows into it bending it back down so it keeps a flat canopy.
