The 2 look deformed probably from bad genetics or a bad seed. Your perlite looks fine, you generally want it to be roughly 30% of your soil but since it is usually inert (if you bought it like that), it won't do damage. It just aerates the soil and allows more water to flow.

Thanks mate i pulled the 2 duffers out this afternoon and am left with 3 healthy lookers, cheers 4 the advice.
