i dont think you should worry the seeds are probably good, plants usually start forcing male flowers/seeds once the buds are really ripe or have been flowering for a good while. . where your conditions not good to where it would stress the plant and turn it hermie? or exposure to male plants? i had a female clone already flowering turn hermie on me once becuase of heat and humidity (learned my lesson).. and as far as weight, if its already dry i dont think it will loose much more weight. . few points maybe. . by the way. . nice grow the buds look very cheese and sticky, i will be getting a couple cheese clones an about a week unfortunatly they are greenhouse not big buddha. .
by the way nice grow .
