Okay, so I sprouted six seeds two weeks ago. They were transplanted two nights ago from 16oz solo cups to 5 gallon pots (the plants from seed to now along with the details can be seen in my grow journal through the link in my signature), and moved from my cfl grow chamber (under 4x45actual watt + 1x23actual watt) to my new 1000w grow room (dual ballast, currently set to HPS). I had some timer issues, so they got more light than I intended, but are now set to 12/12. So here I am, two weeks from breaking ground, and I'm starting flower. The main reason for this is I would prefer to finish and chop before my vacation in mid-May. A bit of an experiment for me, I guess, because I haven't tried 12/12 from seed before. I'm using Advanced Nutrients. I currently have Sensi grow, Sensi bloom, voodoo juice, b-52, big bud, bud candy, sensizym, and bud ignitor. I fed them a 1/4 dose of the sensi grow, b-52, and voodoo juice at day 8, then two days later, just water, then when I transplanted into the 5 gal pots, I presoaked the medium (promix) with a half dose of sensi grow, voodoo juice, bud ignitor, and b-52. So anyone who has done 12/12 and/or used Advanced Nutrients (especially those who have done 12/12 while using AN) I am wondering about opinions as to which combo of nutrients I should use next? I was thinking they will still need a lot of nitrogen so maybe I should give more sensi grow instead of switching to bloom already... the "PK" part could be supplemented a bit with the other items like bud ignitor and big bud.
If you are doing 12/12 from seed I would only use a light dosage of veg nutes for the first week, and after that switch to full flower. If they are indica I would probably start with flower nutes right from the beginning.
