If you have another transplant planned?...do it now....and veg another week.

Once you go into 12/12 flowering cycle the root system does not grow much any more. If you start flowering with a root system, that has not fully developed in the current pot?...it will not develop to it's full potential....IMO.

The roots are the key to success.
