Thanks namvet. I reckon you are right. I have taken photos and will post them when I figure out how to but in the meantime, I have just checked them again now 18.00 Hrs after checking them at 08.00 Hrs and the yellowing in places is mere millimetres from the buds. I cant wait any longer, I will have to chop them regardless of the white pistils.
I reckon Ive got about 10 to 20% amber trichs which is more than Im happy with.
This is really odd.
