Is this the beginning, middle, or end stage of the flowering process?

This is a picture of 4 marijuana plants.
Plant 1: Granddaddy Purple - Height - 38 inches
Plant 2: LSD - Height - 27 inches
Plant 3 Jack Herer - 35 inches
Plant 4 Cafe Racer - 29 inches

I actually forgot which picture is for which plant but if you could give me a rough estimate on where each plant is in the growth or flowering process that would greatly be appreciated!

You're still quite early. Depending on strain probably 6-8 weeks left
