When plants are genetically mature and ready to flower they will show sex in veg which is called pre flowering. They do not start flowering until they actually go through the process of forming buds.
I have ran the same strains for years at a time and they will have preflowers all over them in veg. But never actually flower until I let them.
Getting all cloudy at one time is nearly impossible, so some people prefer a few clear, others prefer a few amber. I lean towards a few amber because I've seen how much plants bulk up the last few weeks and hate missing out on yield.
You'd think, but no (you're not being arrogant). The first white hairs are sign of a female mature enough to flower (I get that in veg). Week one is when you can see actual buds starting.
I have a week and a half left of just straight watering with no nutes until I cut my plant down and my buds are so small?
could this be because I didn't have enough fresh air entering my grow room. I kept the door closed with just a fan on in the room and a 600watt mars hydro light?
