Flower for my first grow

Hey guy just wanted to show you a little of how my first grow is going. I've been in flower for about 4-6 weeks didn't really keep track:/ but they are looking pretty good I think feedback is always welcome and tips as well cheers!

What strain? Looks like they are getting ready to take off. Looks like they are younger than 5-6 weeks, but I guess it depends on the strain. That led looks like it is penetrating nicely! The lower buds look good, IMO.

The strain is northern lights and Durban poison.
Yea I mean I switched it to 12/12 about 5 weeks ago but I messed up and didn't note when I flipped over. And thanks I'm hoping the buds will fatten up. First time so I'm kinda just learning as I go. Yeah lower buds are getting good penetration from the led from what it looks like!
