wow man, amazing what your doing with you 4x6 space! Funny how there are so many similarities, Im also running coco with H&G nutes and I have a 400w and 600w, and my space is also 4x6. It must be getting hard to move around in there by now without getting all covered in resin lol. Looks really good in there, this is quite an ambitious project youve undertaken, Ill be staying tuned till the end. Feel free to check out my thread in my signature, I just put up quite a lengthy post describing all the details.
What's the height in your room? How tall are all the plants now that they have finished stretching?
