First time. Time for some Sour Diesel!!!!!! 4X8 Sun hut with 2k watts of light for 20

Yoo!! this is my very first grow ! Decided to start out kinda big. Go big or go home right, well I guess Its a little of both since its in my garage. I'm running a 4x8 sun hut doing 9 per light plus two stragglers(just don't have it in me to kill the girls). Coco/perlite mix, a lot of perlite so the pots would dry out kinda fast. 3gal pots. I feed water feed water, full strength nutes and I have always fed them full strength, I use cutting edge three part plus calmag, protekt,aqua shield. And when I water i used phed tap water with Clearex. I feed water feed water Usually feed, wait three days then water and wait two days.They are under two 1000 watt lights inside of two Xtrasuns. Temp right now is around 75-78 but its usually low 70s lights on, lights off it stay s 68.The girls are 3 and a half weeks into Flower, I flipped them on December 5th and its December 29th today. They got a week under a t5 and a week under a halide for veg so two weeks total then flipped. I've been told their a bit stretchy so I'm trying to stop that asap, they have slowed a bit lately so I'm hoping im through the worst of it and It will all turn to bud growth! Cant wait to see those fat juicy buds!! I'm planning on updating this ever FEEDING. So about once a week I'll post pictures of the girl's progress. I'm ALWAYS open for suggestion and feedback, even if its negative. Like I said, I'm a First timer so I could always use the advice haha. Check out my girls and tell me what you think!
I posted a few pictures of the plants and set up.

End of week 4 - day 27


So I fed last night full strength and also did some major branch thinning and dropped the lights a bit, The tallest top yellowed up a little bit (its like a dark lime green) when I went in there. I;m thinking I might need to raise the light up, maybe an inch? Or tie that one top down since its the only one being affected, Any advice?? On a good note I think they took the branch thinnin/feeding well. trichomes are already starting to pack on~

So I got the week's wrong my last post, that was the end of week three. Heres pics of the buds at the start of week five!
Hit them with the beastie bloomz four days ago, they took it well as you can see!
4-5 weeks to go!
