It's not recommended but if you get it in now before leaving it any longer you'll be fine.
Just be mindful with what you are taking.
Thin out the top, as the goal is light pen, you don't wanna be removing any growth thats on the lower sites or not covering bud sites as they are a source of energy for the middle and lower parts of your canopy.
So, only if you have to. Go round the top and a bud site will have 2-3 fan leafs with a mix of sugar leafs. You don't wanna remove all them keep at least 1/2 of them and work you way down the node and open it up and as you get lower just leave it be.
Feel free to DM me if you need me details.
Good luck.
