Hi all, iv decided to grow a couple of seeds on 12/12 cause 1 of two of my bagseed has turned out to be male I think, they've been on 12/12 for a week now and already showing, this is my question; should I feed my seedlings with grow fert for a bit? How does it work for nutes if grown 12/12 from seed? thanks.

I know they shouldn't have nutes at first, my soil doesn't have anything in it, where I'm confused is, am I right in thinking that it takes 4 weeks for a plant to mature? Or will it take longer cause they're not having 18/6? Cause if it is 4 weeks should I just give them bloom feed when they're ready for feed? Thanks for the reply.
 
Yeah, I'd be super careful with the nutes, those little ones can burn easily. If you are experienced, and have a TDS meter and such, you could give them very weak "ppm" or "EC". But, you really gotta know how to judge what a plant will take, and different strains will react differently. To each their own...
And, I think forcing flowering without giving time for pre-flower can increase hermaphrodite tendencies, if I'm not mistaken. Putting them on 12/12, so soon, could also make maturing take longer, too.

I would keep em 24hre light for about 4 weeks.
Plants wont flower tell then anyway an youll be giving em twice the light for it to veg an have alot less stretch..

I also foliar feed my lil seedlings 1/4 stength veg nutes. Its pretty safe an gives em somthing.
goodluck grower..

Ok guys, I realise my first post maybe a bit confusing, my seeds have only just been put into pots after germination, my original plants 2 bagseed and 1 white rhino clone have been vegging on 18/6 since half way through jan and put into flower 12/12 for a week, 1 of the bagseed is male so I'll have to ditch it, to make up for the male I'm gonna put the 2 seeds in there aswel but they will have to be 12/12 cause the others are ready to flower, it is a bit of an experiment , I'm not trying to force flower cause 12/12 or 18/6 the plants will mature when they are ready, I'm not gonna burn the seedlings, I'm simply trying to find out, when they are ready for some nutes, should I give them Nitrogen feed or phosphorus cause they will be on 12/12? Should I feed them with N until I see pre flowers then swap? Thanks for taking the time to reply guys, if anyone has grown 12/12 from seed, id be greatful for some tips thanks
