Yes your light setup does provide an even light spread for your space, but that doesn’t mean that your corners are gonna be the same as your center, they will be darker regardless you just gotta work with it, as technically the best you can do is have light directly over or in the edge to counter that but still one side of your plant is still against a wall that’s providing no light or ability to pass light. The back why they are stretching is probably again because they are by that exhaust vent that may be grabbing light and also jammed against an edge which does not have light directly overhead, they are fighting themselves and it’s probably darker to them back there than elsewhere thus they stretch for more light… Sure some air issues could be present but that’s just an add not a main cause.
But yes your destiny will be the most dense where the plants are smashing against and fighting against each other, as they are just trying to spread out and got crammed into a smaller space for their foliage than what their roots can support and to add to that they were given a sibling to fight that same space for.
Straight to the point your pot volume is too big for your space with how your watering and your choice of media, your plants wanted to be bigger than what you could provide space… better to be on this end of the spectrum than the other as its easy to tune it back on subsequent grows. Consider this, some of my plants that utilize 400ml of canna coco are the same size as your current plants with fill levels 16-19 times the volume of them. Thats a shit ton of root space capability, again with very similar light setups, grow space size, watering styles, grow medias, and nutrient bases and not to mention you gave them a 4 week or so veg time too.
Your plants were just trying to outgrow the space, as you gave them the root capabilities to do so…
On to moving them, sure doing that is actually better but it’s just a rotation from our perspective, but how its better is it will allow you to move the plants back and not have to have some hokey ass lid support like i was initially thinking, but instead they will partially bridge the two containers on either side which leaves them in place with their lids and the only thing you’ll probably have to do is throw some tape over the edge where the two container meet that way any run off from your fabric pots will preferably run onto your tray lids and down your drain holes, instead of down the crack between the containers, just overlap some tape over the lid lips.
Reason i want you to get that one side of the plants off the wall, or door if you rotate them is you have a bunch of space going to waste on the opposite side, its empty space filled with light so you might as well use it and make best of it, no sense trying to get the plant to stretch over even further when your at 5 weeks in, they are just concerned with bud building by the looks of it.
If you shift them so they are more in the center it allows two sides to grow vs one as the one side thats against the wall/door will get more light and that will help build those buds while providing some space for that side of the plant to grow, the opposite longer woven side isn’t really losing anything in the process doing this it’s just getting the space that It can “potentially” grow into reduced, but that doesnt mean its gonna fill it though. Consider it’s easier to have a plant just grow out naturally in as many directions as possible than it is to force it to grow in only two directions such as left and up toward the light.
Let the plants do the work for you, as really your just there to provide guidance, not tie them into submission even if needed at times.
Lots to think through here and digest before looking to adopt.
not a good thing from all I’ve read.
…not sure whether this time or the drying time is my most anxious. 
yup. Hard to sit on ones hands… trying to be patient though.
Glad you’re smokin’ your weed…
