About to breed feminized seeds

[Alkemisti]

Hello Icmag breeding section!
I'd like to produce my own strain but I have question before I begin.
Up to how many weeks can the plant be in flowering before starting colloidal silver spraying? I couldn't find any info about this but some sites say that as soon as pre flowers form - some say as soon as light cycle is changed to 12/12. .
But can I still start and have success with producing male pollen from female CBD silver lime haze autoflower that has been showing pre flowers for a week and is about to show real flowering stage - or is it too late?

Here she is

Pretty little sativa



I am attempting to breed strain with resistance to the elements, - that is fast flowering, suitable for latitudes of up to 60 northern or even higher.
As you can see she has started pre flowering and I still haven't begun spraying her with silver colloidal liquid - I will begin it from today, she is just 7 weeks weeks and starting second week of flowering. This is my first time to produce male pollen from female plants - all advices are appreaciated.

My colloidal silver is 25ppm is it any good or should I just forget it and do it some other summer?

Is it way too late for 7 week old autoflower - I will wait for you to answer before I start any treatment on her. .

You want to hit autos as soon as you can because you have a shorter window to have the seeds mature. You'll probably have to keep it alive a lot longer than you would harvest it.
