Too big plant and supercopping in flowering mode

Hi.

I m new here and English isn't my language, so excuse me for my grammar mistakes...
I was done some searching, but I didn't find right answer so far and because of that I started new topic.
I have 8 different strain plants in one smal grow closet(60x100cm) and one of them is going to be much bigger than others. So is ok if I do some supercopping, just the upper 5cm of plant? I would like to slow it down a little...
Plants are around 3-4weeks in flowering stage and they are already developing some nice buds. Plant is Royal Gorilla from Royal Queen seeds.
Can anyone confirm my idea for usefull, or should I use some other better solution?
Thank you.

Yes, you can do this. It will slow the growth of that cola but if you're running out of headroom, it's the only option.

Good thing too is your stretch is nearly done on the RQS Royal Gorrilla.
I've been growing it for a good while now and they don't stretch very much. But then I grow bushes rather than single cola plants.
As @GBAUTO sez there's no problem supercropping it.

Thanks, I`ll try to supercrop her in a moderate way, gently

Oh, hell no...
Bend that girl over like you mean it.
sorry, ladies

I did it and the top is already straightened up. So far so good. The plant does not showing any negative response and I hope it will be nice Gorilla girl.
There was a battle with fungus gnats, a lot of them, but it sems like I won, at least for now... I think the main problem was overwatering. I used some H2O2, neem oil, diatomaceous earth, Nematodes and a lot of yellow sticky cards.
On the second pic is Gorilla with a Cookies in front of her and the Crittical on the left and Skunk XL, ICE, Domina all from RQS bank. On the third pic is Ultimate from Bulk seed bank. I made some mistakes, obviously and she turned almost complete yellow and had stunned growth.
Because there are seven different strains(searching for my personal best strain) , I have/had some problems with height adjusting, if I wanted same height of the most top buds, but now is ok. That is also why I have so small pots, like around half gallon(cca 2,5l pot), except one bigger 8l Air Rap, which was planted few weeks earlier...
