Ive never really grown plants this tall before, so hopefully they don't end up with too much popcorn. I have done a bit of cleaning around the bottoms to help the cause.
Thats why I was saying to use a cpl lights vertically, If you put 1 400 vertical right at the center to top of the canopy then take the plants and put them around the light, the light will penetrate into the side and bulk up side branching. So all you have to do is spin the plants around the light so all sides get light. It might seem like more work but thats the difference between buds and popcorn.This plant here is 3 inches from the top of my box which is 39 inches high so thats over 3 feet not sure how many cm that is but its probably as tall as yours now. just my opinion. keep it green bro.
