split or trained too hard??

1st time growin indoors so i thouht it would be best to open up the plants from the top...i guess train em...I did top them at about 3 weeks from seed so they devolped double stems as it is off main stem...i have noticed that 1 of the stems, only 1 plant, is startring to split at that point ...almost hangin from the main....looks really healthy tho..sould i cut now??... just brought em into 12/12 so worried bout the weight of nug on em later....should i tie it...like i mentioned the stem is half attached and lookin good no discolaration or nothing

I'm unsure what you mean, can you post some pics?

there sleepin right now but definitly tomarrow...i am gonna also start the bamboo supports tomarrow....but was wonderin if i should just cut it and let her spread her streagth to other more valuable parts..instead of keepin her

By cut, you mean trimming some leaves off? Still kina confused ... :S
