How long before you plan on doing the light switch? If its soon (less than 2 weeks) I would top at the 5th node to ensure all your branches are fully developed to support bigger buds. If you have more than 2 weeks veg to go, it'll be fine topping at the 6th node. By then, those tiny tiny side branches that are just developing will have had time to mature to produce those THICC colas.[/QUO
Oh yeah they're short just a little bigger than that pic at least 2 or 3 weeks to go I like them bigger.
Get that topped now, i prefer just above the 2nd node.View attachment 4017639 If you only topped each plant once when would you top after the 5th or 6th nodes is my choices ? After triming off the bottom 2 nodes the 5th node will give you 6 colas or the 6th node will give you 8 colas!
I done 4 before you get bigger colas the fewer you have~Get that topped now, i prefer just above the 2nd node.
