pics When do I pinch out tops of seedlings?

Is it time to pinch out the tips of these seedlings?

Looks like it to me. I would if they were mine.

Maybe I will top my small ones once up planted to the first set of leaves. Is there a specific Bonchi guide?

Jukka of Fatalii Seeds has a good guide, and generally seems to be the energy behind the bonchi phenomenon.

As soon as they grow 3 sets of true leafs go for it...
