Well if you want anyone to help sex your plant you should probably take a picture where the preflowers show up, at the 4 internode or up and right in the corner right behind the stipules. Also why dont you just wait untill your plants show preflowers during the 18-6 or 24 hour photoperiod. If you trigger flowering before this it is fine and many people do this including me but on my current grow my plants are 55 days old and now showing there preflowers as soon as i can determine there sex by the preflowers I will pull the males and then trigger flowering. I waited till I saw the preflowers this time instead of just triggering and obviously the plants are bigger and studies say they will be more potent if you wait untill the plant has there own signs of being ready, such as distinked preflowers and alternating nodes
