5 ft is tall for an indoor grow , it's hard to penetrate light down that far . Experianced growers who are not lacking in skills in any area can pull it off . The general idea is to keep them nodes as tight as possibble for a shorter plant that will form long solid colas.
Good work though bro ! Give yourself a pat on the back , many don,t do as well as you have. Looks like you keep em green and I dont see any major leaf problems . +rep for the first grow !
