Sounds odd 

Any chance of a piccie?

Now that the seeds have been propagated, no need for them to be in the propagator. Let some air get to them.

Some plants are a bit green, reddy and yellowy to start off.. a bit streaky at times.

Almost sounds like some sort of virus or something in (or not in) the compost. Take them out of the propagator and give them a dilute liquid feed such as Maxicrop and see if there's any improvement. Meanwhile, I'd sow some more just in case.
