Try to wait at least one week, aim for two weeks, before you flower a topped baby. Give those tops time to grow. If you flower them now, they are just going to be small tiny and shitty.
cuz its simply not true. i top em all the time after switching the lights to 12/12 and i get nice big colas. they stretch for a couple weeks at least after switching to 12/12.
