pull out the roots below your rockwool of the males. If they are caught in the roots of your other plants, carefully remove them. Don't worry about breaking and losing some roots to the plants you are keeping. Roots can be trimmed without damage to the plants. You can even cutt all the roots back to just above the water line. Some people have had bigger and better results with this.
