I have only planted these this year, there in a unheated plastic greenhouse, I am able to take the powerdy stuff off with my finger but it just comes back, I have notced that the the leaves droop the moment they come in contact with it, Im a new gardner so sorry if I have made a mistake!

It could well be that your plastic greenhouse means poor ventilation which would encourage powdery mildew so make sure you leave it open on mild days but don't forget to close it at night because they don't like to get too cold.
You don't say where you are but my new pomegranate - planted this November - is deciduous and leafless at the mo here in western France.
Have a look at this info from the RHS which includes advice on teh correct compost, temperatures, light levels etc - https://www.rhs.org.uk/plants/14189/Punica-granatum/Details
As Obelixx says above, it's too damp/wet and there's a lack of airflow that has allowed the fungus to get a hold, but it's not powdery mildew.
The conditions in your greenhouse are not what the plant needs.
Basically it's too damp and possibly too cold for you plant so it has become weakened and the fungus taken advantage.
Where about do you live?

I am in south east UK, In the morning I will (try) to do something about the damp but as its a plastic greenhouse im not entirly sure what to do about it, Im not sure about too cold as all the reserch I have done (which is all very conflicting) has said that it can take up to -7 but we havent hit that here, I will also leave the greenhouse half way open in the morning to see what happens, thanks!
They are young plants and are not ready to survive the great outdoors just yet.
Bring them in and let them warm up and dry out a bit somewhere that gets good light.
Trim off the bits that are badly affected.
No point in using fungicide (especially on such young plants), you need to improve the conditions for your plants and they will shrug off the fungus.

They tend to create a damp environment, and don't really offer anything other than protection from rain/wind. They don't have the kind of insulation a proper greenhouse has.
I live in west central Scotland - not where that photo is...
Try sprinkling a light dose of ground cinnamon on the surface of the compost and over the remaining foliage once you have removed the worst affected. I haven't tried this yet my self but am planning to use it on trays of seed compost this spring as some crops are more prone to damping off, a fungae that kills seedlings.
Another remedy I've just read about but not yet tried is to spray with chamomile tea. 1/2 cup of chamomile flower heads to 2 cups of boiling water. Leave to steep till cooled then strain and use as a spray.
okay I will give this a go, I have brought a glass greenhouse but it will take upto 18 weeks! to come
I have recently brought myself a glass greenhouse that has a a window and all the rest, but Ive only brought it a week ago and they take upto 18 weeks to come
