The fact that it is 6 weeks old and hasn't flowered is good for an Auto..first impression is decent genetics..If you grow out more of those same seeds..20+ hrs of light start to finish (including during flowering)..you'll know whether its worth growing in the future
Be patient my man and if nothing shows after a month and half it might be a reg photoperiod .Then I would change to 12\12 and after a week of that lighting you should see flower signs.
