They,ve been under 12/12 for five days. I know it takes time but how long till I should really start looking close. Early Fatty from bcseeds. Am I right that males usually show first?
i don't know if males usually show first, but it could take another week. depends on how long u have had them under veg too. if they are reall big they will show sooner than a little week old plant. be patient though and you should see within a few days to a week
Males often show before females, but I personally believe this has to do with males being easier to spot (green testicles, anyone?). I always see preflower growth to be nearly uniform in the same genetics but a second ball usually shows before a full blown vagina-like pistil protrusion. You should start looking close now. For an average veg of about 35 days, I would expect to determine sex within 10 days. This is, however, strain dependent and many people have to wait as much as a week longer.
You will notice a tiny little sack usually after the 4th and 6th internodes. They will be small at first and pisitls almost invisible. I would say you got anywhere between 2-7 days to show.
