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
