well i just top my plants once,never tried messing around to much,but once was always good for me.since you are growing "mexican" weed does it turn to white man weed? joking sorry.

but with an unknown strain anything can happen and hermi tendancy is VERY high,just dont stress it out to much best bet since you topped it once already just tie the branches down.not much else you can do..

how many you got going...

the outcome might not be very good..

i would suggest order some seeds from a seedbank 'very easy and not much of a problem..

get some cheap ones to start go with "kc brains" check my threads in my profile for mango that was kc brains mango outdoors there are others like mandala seeds wich is very good also,and i think are 30 bucks.plus get stealth shipping another 20 something bucks plus free seeds usually one fem from atitude.get some within the month nd you can get a decent harvest still.

for you current grow to make them flower faster put a black bag over them at the same time every night and take off every-mourning at the same time to trigger them into flower and harvest early!!
