Are these nearly ready?

Hi all,
This is my 2nd grow (1st one worked ish)
These are F1 milky way plants and are now about 9-10 weeks old.
Please forgive my dodgy camera work..I really struggle with this part lol.
Are they cloudy? White? Can't see any amber?
I just don't want to overcook these as I think I did with my last plant.
Also could I harvest the top buds and leave the rest fill out some more?
I'm still feeding them regularly and wonder if I harvested the top they haven't been flushed? I don't really know what I'm talking about sorry.

Few weeks based on the bud structure alone.

Don't worry about flushing.

Your doing good and it's a good selection of pics so we can see what's what

Thanks mate..just don't want to leave them too long this time
