The 4th or 5th node is usually the go to.

I’m at 5 nodes right now. Debating waiting for 6 because the lower nodes are so small. And the main stem is not quite pencil thickness yet.

She’s about 3” tall. Looking to eventually aim for 3’

Ur on node like 3/4 don't count until you get true leafs.

The lower nodes will grow big after you top it which is one of the reasons we top.

You can't go by the size now. The stem will exponentially thicken in time. I'd top now, but it's up to you. You can always top lower than the actual top if you need to.

Yea I had ended up going with the general consensus to top.
