Outdoor Growers - When do you change nutes to bloom?

[furlee]

Growing outdoors for my first time in Norcal, was wondering when I should change the nutes over away from the high N veg formula?

I have a satvia that is already showing herself and beginning the probably 7th day of flower as of today and then I have a GDP that hasn't really started budding yet, barely barely showing pre-flowers.
Anyways, thanks for the help in advance

I think the general rule of thumbs is to wait until your stretch is over before committing straight bloom nutes

OK, thanks for the help. I'm getting good stretch on both of them but the sativa has blown up in the last two weeks/10 days.
