yeah actually had the same issue on 5 autos (3x auto ak, 1 auto diesel, 1 auto ultra violet) they didnt sex till about day 30-33, switched them to 18/6 and they started to flower the following week day 35-39...still currently going on day 48-52

thanks for the info justice its not my first 24/0 just the first time with problems i might have just lucked out the first times around i have noticed if your running high wattage there kinda forced to flower i guess i dont know honestly i guess even the stable strains have some hiccups on occasion
