She looks perfect for a topping, and where I did my four in my second journal. All seem to have loved it.
You could try opening up the next node a bit and seeing if you can do a microtopping on the four, it's likely already there. Too delicate for my fat fingers and coffee shakes, but you might have better luck. You'll know quicker if it worked or not, and can always fall back to just removing it back at the top node you have now.
Just my thoughts, inexperienced as they are.
Oh, one other thing, I've found bending one way then the other works better for me than cutting as it allowed me to stay farther away from the delicate new growth tips that will become your new tops.
It's a nice thing. 
Thanks arteekay,
My teeny tiny fingers work pretty good with topping, my fingernails come in right handy. LOL The last time I was going to top an auto I had a little trouble with stunting it, by the time it got big enough it had already gone into flower. So we opted out of it. I want to be hoppin' ready this time.
I looked at the top node, I could easily top it, but wanted opinions on whether to wait a bit or not.
You and I keep running into each other...everywhere.
at work for sure.

Sonic, space isn't an issue. There's plenty in that room for an auto. Not sure if I'm going to LST or not, I want to see how it structures out first. I think the next one in the room will be LST'd just to try it. It's too bitty yet, just sprouted a few days ago, it's a Fast n Vast auto.
Oh yeah, I hear ya there. I LST and do some topping on all of the photo girls. It's quite relaxing.
Autos are new to me, so any and all help is greatly appreciated! My first two tries were not what I had hoped.
Oh stop that!
It's different with them because of the time frame. Photos can be manipulated forever in veg, Autos....nope. I appreciate your input.
Do you do a 20/4 light schedule for yours?
what a beauty.buds forming well 
these girls i have not backbuilded.but normally i back build all my girls works a treat.and the towel is cause that plant is sat in cheap general compost so come feed day i drop a litre she can never hold it.pisses out the bottom hence the towel let it soak it up then remove it.soil is crap shit drainage but was a challenge i set myself.she is happy so far
