She has already started flowering and is looking good buddy but i would be careful with transplanting once flowering has started - you might induce unwanted stunted growth, and with your buds, losing 10 - 20 days can impact on your overall yield/quality.
I would suggest either to use the 2 pots technique - Take another pot of the same size and fill it with your growing medium only at 3/4 full (make sure to include some calcium in the medium like crushed dried egg shells which your plant will need later on in the flowering stage). Then remove as much as possible from the bottom of your current pot without letting the plant drop and without damaging the tap roots. Once it is done, put the first pot in the second one that is 3/4 full - Give it a good watering and do not move the pots for a few days. Roots will grow down in the second pot. However, if she is already flowering, there will not be much additional root growth.
Or, If you have the space. and the soil in your garden, just dig a big hole and put the whole pot inside and cover it up. Before doing that repeat the above process but also add some side holes to the pot prior so roots can grow sideways too.
Good luck!
