you know i think you're the man, but I'm gonna hit ya hard with this one... I feel you should wait three weeks to chop.
now if you're out of bud and really want to smoke it, then chop when ya want.
Or, If she is jamming up some motion in the cycle and you need to rotate veg out, then chop when ya want.
but her trics look pretty clear yet. and a plant can almost double it's yield in the last couple weeks.
It's your plant though, and i don't doubt your skills one bit, so if you think she is ready, then go for it. maybe wait till next wednesday and decide then...
