Topping plant after 2 weeks

Can i top my plant at 2 weeks from seed? And how do i? I think i do, i have to cut the middle stem with the crown on top right??

could you? probally. should you? NO. wait till week 3-4 at least. you could start low stress training now which is better that topping, cut the main stem right above the top node or u can fim where you leave 20-40% of the new growth on above the node. makes multiple top colas. info is in the faq up top friend, time to do some reading.
