topping for scrog closet

Alright folks my babies are about to be growing out their 5th node gonna top at 2nd node to create two tops sounds about right correct? (gonna clone tops) I will then top each of these tops also at 2nd node (which im gonna do once third node pops) then take it from there im on day 13 since they popped which means my time table is actually working out my goal is to flip on day 28 maybe 35
