All uk growers check out my journal

Hi guys.

This is my first time grow and wanted some feedback. Plenty of photos and not too much to read!

https://www.rollitup.org/grow-journals/84840-first-time-grow-outdoors-uk.html

The plants have been on a 12/12 dark room cycle for 7 days now. Should I start on the flowering nutes even though they are not all showing sex yet?

All answers and comments in the journal pls

Thanks guys...
