All (except one!) of my recently planted cus indoors have got it.

No - not RSM. No sign of any infestation. They just do this & die off.

and do those spots turn into holes?

My cucs were doing that but since they have had a weekly seaweed feed they have been OK and I might even get a cucumber this side of Christmas ::)  I blame the dodgy compost.........

My usual stand-by of Ask Jeeves images let me down, but I did find this which may help

It's amazing we ever grow anything.  It's a war zone out there!!

No, SMP - they just yellow & go to paper.

Don't like that one bit!!

So what do I do about it?

Hi Tim, If it is septoria which it looks very like,, It is a fungal disease ..How about  giving a couple of  the plants a good drenching with Bordaux or dithane ?To see if it stops it spreading any  further up to the healthy leaves...

OK!
