The bottom cotyledons don’t count as a lobe.
Usually I don’t count the next one either. I start counting nodes when the first set real leaves (usually 5 lobes) develop. In this case #1 may be in question.
Plant looks good. Since it is an auto I would top where the red line is. When you cut, cut about a 1/2" up the stem so there is a good stump showing. Good luck
I need to correct earlier post. I should have said multi-lobed leaves i.e. 3 lobes rather than saying 5 lobes. Once it produces multi-lobed leaves start counting node.
Sorry for the misstatement
