I even swung to a 2700k CFL to assist with flower 6 weeks ago because the Bubba is being stubborn…lol…
And not femmed seeds or clones…
I don’t own any cannabis growing books, I have read a few from the library, I find a lot of them to be “not real life experiences”, however, there are some good ones.
I learn from fucking up, then do it again
Idk man in my experience around 6 sometimes longer weeks of veg they will show sex with preflowers without changing the light schedule
Ya I find some as early as 4 weeks most by the 7th week even resistant to tell strains.
Transitioning stage
Its preflower stage its the plant telling you its mature enough to flower its how isex mine then once everything has shown sex then i scrog wait a week then flip to 12/12
As for personal services, there are many different options among them.
