Does anyone have a link for strains an their flowering stages an everything ?

There are many factors that come into play.

If you're growing a photoperiod plant, vegging for a minimum of 4 weeks is a general practice. Some strains require 3 weeks and you can veg for as long as you want in a controlled environment. The longer you veg, the larger the stretch will be in flower. Flowering will vary from strain to strain. The best way to know is by checking the breeder's recommendation on their website if you ordered online. Flowering can take anywhere from 6 weeks to 12 weeks.
