i know this is an old post but some of the responses pissed me off a bit, because they do NOT know what they are tlaking, about, to the OP if your still around (doubt it xD) plants can and WILL switch from indica leaning to sativa leaning after flowering is triggered, but it NEVER happens the other way around...here is a VERY good example
i think your all idiots lol...my current grow when it was 8 days old
and now the SAME plant when tewnty something days old
and now what the flowering tops look loike....wont change my ASS
the new growth is looking damn near PURE sativa, and this plant started as the SINGLE HEVIEST indica dominant looking plant ive ever had
things change, and plants will too, even over the course of a single plants life
