Can I top her at this point

I have a strain that I've had in vegetation for 10 weeks. I'm wondering if you can still top a plant this far into vegetation and if I'm going to be putting her into flowering phase in the next couple of weeks,will it even be worth topping her?

You can top anytime in veg, just give it 7 to 10 days mininum before you flip, so the branching can start. I generally do my last topping with at least 2 wks to go.

you can veg a marijuana plant for years if you like, and top them a hundred times, or none at all even, every day, or every month no matter. I often top the day of flower onset with no issues, but do try to plan better to allow new chutes to form first .
dont top in flower, bend, twist, tie down, just dont top her in flower
