I stopped giving her nutritions at all, since the harvest comes nearer. I'll flush her for the rest of her days with clear water :) She looks almost ready to me but I'll wait another week or two and watch her trychomes.
UPDATE: when I wanted to give her water I sw that she still was wet and so I didn't give her any more. I guess that's ok since I could even stop one or two weeks before harvest... She still looks great :D
