Blastula is a stage and it turns into a foetus on maturation.
The germ layers are formed in blastula or better to say blastula gets differentiated into germ layers. It is not like blastula turns into germ layers on maturity because blastula is a name of stage of embryonal development. It does not matures it gets differentiated and step into next stage.
Hope it helps.
