lower leaves are yellow

[dandanbo]

For 10 weeks you must have started them under 12/12 lights? Either way those plants look close to being finished and the yellow leaves look fairly normal to me at this stage in the plants life. Transplanting probably did more damage then good, plants tend to go into shock when they are transplanted. I'd suggest trying some superthrive to help with the shock of transplanting. There really isn't much more you can do at this stage other then to let it finish. You don't want to use any nutrients that last two weeks and I think you're getting very close to that stage. You might want to lower the PH a little as well.
