Sulphur and poor smells from fermentation sounds like nutrition problems - and Kveik is quite particular to FAN (Free amino nitrogen).
Richard Preiss (of Escarpment labs) recommends 180+ ppm of free amino nitrogen when using Kveik. FAN is naturally found in malts, but some malts (pilsner for example) have less than other malts. If you are brewing a low gravity (1.050 or below) beer or only use malts that are low in natural FAN it is recommended that you add some yeast nutrient.
