it depends on how many plants you have and your space, but 3/4 of that plant should be a single cola so taking off one or 2 more sets would inprove the main cola but there wouldnt be alot apart from one main cola,
Dail, i always lollipop mine for a sog at 3 weeks 12/12 works grate for maincola building but it will add mayb a extra day or two on your flowering time (recovery)
