If you get pictures it will make it easier to tell you if you should veg for another week. It's really a personal thing, plus it also has a lot to do with your grow room set up. Second as far as the transition between veg and flower, you should flush with just ph H2O for two or three days to remove the build up of the salt's that have been left in the plant form the veg fertilzer. I like to flush with Ph H2o and a mild flushing agent. I aslo grow in DWC/KBS, hope that helps.
