stunted growth seedlings

hey guys,

I have started my new grow about 6 weeks ago from seed... however i noticed a stunted growth for all the seedlings and to my amazement i noticed 2 of them were already showing sex -- males! =(

I checked everything... everything seem to be normal except that i had accidently set the light hours for 16/8 instead of 18/6... do you think this could have caused this (stunted growth + early sexing) to happen?

Yup

Oops

yup!

no seriously, yes. Either put them on 12/12 properly and let them finish, or stick the ones that haven't shown male on 24h and veg them until you are ready.
