no worries...it takes a couple weeks after the switch before any real changes begin. 3-4 before you see those popcorn buds then they'll take off and start filling out the stems.
soild advicebut one shouldn't necessarily go strictly by what the breeder info says. i've noticed it's usually at least a week or two short in most cases but it can be used as 'general info'. for instance, every time i've had straight ak47 it's flower time was closer to 10 weeks...
Don't go buying additives now.I just need REASSURANCE on around what week do the actual buds start forming..and the pistils start piling up??
