Im going to guess and say you'll probably pull 3 zips a plant at least being you topped them... You def should of used bigger pots man because that def going to effect yield... You mean to tell me your in Nor Cal and your using mg soil?? You have 100's of garden supply stores around bro...lol...Why?? Im not hatin, Your plants look fantastic but lets just say if you would of went with some ff ocean forest soil and some good nutes, you would easily double your yeild IMO.... Either way your going to have some good smoke....
