Not much, often the first few leaves can be a bit strange while the plant works out what life is all about.
She should grow more normal leaves soon enough
Remember too, no plant will ever have 100% perfect leaves, 100% of the time.
Cannabis is quite prone to growing odd/weird/strange leaves, with all sorts of deformities, most of which will never effect growth, potency or yield.
Hope this helps, Organoman.
