I'll be at week 8 flower tomorrow, I have 3 plants, some look more ready then others, some have more orange pistils ect... I started flushing one of them because I assume by week 9-10 it will for sure be done? However the other two don't look as done, so is it normal to wait until week 8-9 to begin flush? It's my first time flowering and I don't wanna mess up the flushing
Welcome to GC, hellojellomellon time lines are just general guidelines. If you want the crowd to advise you, please update pictures of your plants (in natural lighting please).
Looks very kind for a first grow, good job! Many people will suggest observing the trichomes (I do), but to do this you will need a digital microscope (~$20), so you may want to invest for next time. Its difficult to say if she is ready without observing the trichomes, but without this data, it looks like its near.
