UK outdoor big bud update

Ok guys an up date so im coming to the end of September im guessing i got to wait till the end of October.
been lucky here in the uk had some nice weather. The big bud has been pretty hardy and i know the one on the left looks poorly but she is still budding ok
the thing i don't like about this strain is the buds don't seem to be that tight but i guess this should all change in 4 weeks
any advice to help my yeald would be great

I would give them some blooming nutes.

By the way, they look great. Good luck with the weather.

thanks dude any brand or a good suggestion on one i could get here in uk i am using bio bizz bloom
