help???

I germed some seeds I ordered from holland on Oct1. I have had them under some lights I got from Stealth hydro... I have been using the veg lights only. I would like to sex my plants and then clone and bud from there. I have had the lights on a 18/6 schedule the whole time. It has been 6 wks and still have no idea what sex they are. When should they start to pre-flower, and do I need to change my light timing? Oh, I am growin in a mixture of scotts potting soil and perlite mix, using chicken shit as my fert, and spray-n-grow on the foilage, doin that every other week!! They are very healthy and happy, just no sign of sex!!!! Any help would be awesome!!

When did you actually plant them? And what strain is it?

No need to change the lights till after u take the clones. Some plants will show sex as early as 5wks, but usually it takes like 7-9

I guess you should switch to 12/12 if they haven't shown sex yet, some strains are stubborn. The good news is males usually show up around 4-5 weeks so your looking good for an all female grow.

idk about that, i had two plants that didnt sex until about 6 weeks in but one that i planted about three weeks into the others grow sexed at the same time. the older two ended up being male and the younger one turned out female. they all sexed after i changed to 12/12. nothing was visible until about three days after i put into flowering.

Ok, so I germed them in pellets, it took a couple of days then when they got their little leaves I put them in some solo cups and put them under the light 18/6 and transplanted when they out grew the cups... I don't know what the strain is, I bought 10 NL and they sent me the 20 free... So, I thought I would experiment with the free first, I am gonna germ my NL as soon as I get my bud closet goin... I am gonna try to feep the mothers and clone for bud... Which is why I am Jones'n to know what the sex is!!!!!!!

I actually planted them on Oct. 7th...
