your making your life really really complicated... dont worry about what happens in nature... if you are controlling the lights you are controlling the plant... the idea that the plants need "rest" because in nature they always get some rest due to night is not a valid arguement to make... the "rest" does nothing for the plant... the growing they do at night is more stretching than growth.. sure there is some normal growth.. but since light is needed for photosynthesis, and at night there is not light, it stands to reason there is no photosynthesis.. so there isnt any reason to try to mimic the outdoors with crazy light cycles.. it just ends up confusin the plant and stressing it out and which can lead to males/hermies/problems... so as far as vegging stick with the same light cycle the entire vegging process... if you start with 24/0 and end up needing them to slow down growth switch to 18/6... this will slow growth down a little.. but as i said keep your light cycle throughout veg the same... i personally use 24/0 and swear by it... the plants just grow the entire time... basically there is no REAL reason to have any dark period during veggin except to save money on electricity... secondly i cant stress enough how important light is.. you need more light for sure... but your aware of that so ill move to the last thing... different strains of marijuana have different critical photo periods as i said... the only way you can know for sure what the CPP of your strain is, is by years of growing the same strain... it takes a long time to learn all the little ins and outs of individual strains... so i cant say anything about your 10/14 light schedule after 2 weeks of flowering... what i can say is this.. your plants are mature enough to flower.. they are genetically structured to only be so potent... you can grow 2 clones, one to 4 ft tall and 10 ft tall, and they will both be just as potent... unless you have enough light you wont get a big yield anyways... so dont take hieght into account.. either way your plants have reached max maturity... i would take clones now if you are going to.. or switch to flowering... same thing with flowering.. stick with 12/12... ive been growing my strain for a year or so now and am just startin to think about different pruning techniques and flowering light cycles... but until you have experimented, and to make sure you get the most out of your plants right now, leave it on 12/12 the entire flowering cycle..
so
1) dont mess with light cycles... keep vegging at 18/6 - 24/0... flowering at 12/12 until you get used to the strain... dont worry at all about natures light cycles.. they dont affect your indoor plants.. to those plants.. you are god.. you make the sun rise and set as you please... just make it consitantly rise and set at the same times so your girls dont/cant get confused...
2) when you repot try to only do it once... go from starter cube/cup to final pot... your girls will flourish better.. and since transplant shock can stunt growth up to a week, they will end up growing faster since you dont have to wait a week everytime you transplant..
3) the only, i repeat, THE ONLY time i fuck with light cycles, besides going from 24/0 to 12/12 is this.. when i decide to flower i give my girls between 24-36 hours of straight dark... this helps the onset of flowering by telling your plant without a doubt its time to start flowering... it can speed it up by a week.. which also helps with sexing... i usually know the sex of all my plants within a week doing this... other than that they are under either 24/0 or 12/12...
hope i answered what you wanted... anything else??
