Another week, small update. I measured the intensity of the light in different places in the tent and found it (surprise surprise) that my cheap LED didn't cover the edges of the plant. I tried to tie everything a bit closer together to make the light reach all branches. The lower parts of branches will now get less light, while the tops get more. I'm trying to reduce this effect by folding leaves under the flowers instead of having them hang over, and by defoliating a little.
