TOPping, FIMing, and applying LST techniques will dramatically increase your yield, I highly recommend to try at least one of these methods to make yourself an opinion. Be warned that this may slow down the growth process for a couple of days, enlarging your initial calendar. Also, note that topped/fimed plants could be more sensitive to the wind, because of the number of colas to develop and the new structure of the plant, stems could be weaker than if you let the main cola grow naturally. But I noticed you already protected your grow area from the wind so this shouldn't be a problem. Finally, as mentioned by
@ShaggyGrower, having too-close colas can lead to mold issues, especially for outdoor environments. To resume, I'd recommend to try, experiment, improve your skills, see how it goes, and next time you'll know what to do based on your own experience. Hope this helps, I'll be around, keep us up-to-date and happy growing!
