what the hell man

i am just figuring out how to use this web site i am not computer savy eh.but i need some advice. i got some seeds from online and i got three females but.here is the problom they grew very nice but when you smoke it there is no high what so ever what can cause a plant not to have any thc in it

early harvesting
you cut them down way to early

or you are smoking the males and think you are smoking female
(dont do this on the human level =)

you are smoking leaf and think that what weed is
post a pick of your buds

i left them in there for 8 weeks man 2/3s of the white pistals were red .is white widow a longer flowering cyvcle or what

anyway thc develops as the plant grows these plants are not males i aint stupid. even if i did pick them to early they should of had some thc in them heel i grew a og blueberry and had to cut it down in the third week of flowering and dried it out and hell at three weeks it had a real nice high to it.
