let them be and just let them do there thing, you can try to contact seedsman for answers but it just might be the strain.
autos are bred to be fast flowers and get the buds done quick, it also depends on how they were made. in all i would leave them and just sit back and see, that way i can decide
if you want to grow that strain again, some strains are just not that great. so do not stress. like i said if you want more answers contact them, as they should know about their own strains, or at least i would think they should, hope this helped
