Top leaves bending down

A question from a fellow grower:

Hey Robert big fan of your books and your weekly tips l, I’m currently growing some durban kush in Vancouver British Columbia. I just topped my plants main cola last week and have seen a large number of new branches this week and was wondering if it is normal for my top leaves to be bending down wards I’ll include photos, thanks.

Looks like nitrogen abundance, between top and bottom pictures looks like she was already bouncing back for you
