30 days of veg seems a little short. Is there any particular reason you did it only for 30 days? Anyway It can take 2-3 weeks sometimes more to show the sex of the plant. Sometimes for sativa strains it could take a little longer. Just be patient. and keep checking everyday. And also check and make sure your plants aren't male. Male flowers look a bit like small bunches of mini green bananas. Look near the leaf joints on your plants to see them emerging. If that is the case remove them as soon as possible. You don't want your babies to get preggo with seeds! Good luck and I hope this helped.
i wanted a couple of blunts for new years and i was told 4 weeks was good enough but thanks for the help after two weeks of no pistils im freaking out
if they come from clones yes it is ready ...but from seed takes 4-6 weeks to mature.
long long time sativas... your right with valentines day though, maybe a bit longer..You may have blunts for Valentines. Better go shopping for New Years smoke. Just be patient, the plant will show sex when its ready.
you realize 30days= 4 weeks2days, yes? So that would make them mature by your standards.
dont listen to these fools, your veg time is fine. one reason for late flowering is temperature. both during the light and dark period temperatures should be lower than normal and this is especially for sativas.
How big were they, before going to 12/12? Age is irrelevant, if they were grown very slowly. For example, a 6" plant,(small for it's age) even though it's 4 weeks old, isn't as mature as a plant that was grown properly, and is much larger. The smaller plant will take longer to show preflowers, because technically, it's only like 2 weeks old,(maturity-wise) even though it's been around for 4 weeks.
It's strain-dependant, too. I was just throwing that out there, because I see lots of plants here, that are small for their age.![]()
I agree that 30 days for a sativa is a little early to flip but 18 days of 12/12 is a long time not to be showing pistols or at least have preflowers. This may be a stupid question but are you sure its not a male? You may also have a light leak. Just some thoughts. Good luck my friend.
