I can say this. Plants that I've seen indoors from seed start with one point leaf and go up from there. 1,3,5,7,9, etc. Now can we conclude that's from light? Maybe. Reason being I start with a bulb or two of t5 at sprout and go up from there. Its either age or increasing light as I go.
I also have noticed plants will do the same thing from seed as u go up nodes the leaf points go up.
I have also noticed that indicas tend to stop somewhere between 7-9 points. Sativas tend to get more. I have a c99 outside that is throwing 15 point beautiful serrated points. Also that outdoor plant tend to go up in points faster and higher in points than indoor.
I have also noticed that anything with ruderalis in starts with a point and then goes up but after a point or three it will be 4 or six points and really look funny. Sometimes they stay at three or four.
I will take a pic of the c99 leaf. Its as big as a paper plate with 15 points. Very pretty plant.
