Flowering HELP and some other things

Ok so my bag seed has almost gone through 2 weeks of 12/12. I had to switch it back from a 400HPS to a 400MH because I just germinated a few auto seeds. Anyway I've been having some trouble telling if this plant is male or female. Can anybody out there tell yet? also I think I need to get some kind of intake exhaust for my tent because when I close it just gets sucked in. Anybody else have that problem? my camera sucks so sorry about the quality of the pictures. THANKS






Just noticed a lot of purple on the stems. Does that mean the bud will have nice purple shade to it?

bump please

i think it may be too early to tell on those. Need to get a bit closer and away from your magnetic ballast so the lines arent there. The purple could be genetics or not enough ventilation or gettina little cold.
