Pflanze wächst buschig/große Blätter

Can you tie down the large leaves with a stake so that the tops of the upcoming branches get some light? If leaf tucking isn't enough, I would remove the leaves. The plant will grow slower at first since its photosynthesis area has been reduced, but in the long run, it will grow much faster once the side branches start to develop properly.

Sure but if you reduce 'total' amount of photsynthesis by comparison, it won't help. Try routing or bending around the large leaves. Anything destined to be a primary cola can't be all bunched up anyway, so that early growth canstretch a bit without issue. You only want ~3 colas per sq ft. Usually there are too many and need to be thinned out, More just gets you increased trimming time and smaller, more-distributed buds. Even 2 colas per sq ft does a good job, but the buds are thicker and more prone to disease, so it's a give and take... Think i am averaging 2.7/sq ft this grow. Also reduces what you have to prune off and eliminates any need to defoliate (beyond useless axilla that will take some nascent leaves with them).
