Hello.

I'm growing courgettes in a tub. The leaves are all turning silvery-white,
spreading out from the veins. It doesn't look like powdery mildew to my
inexperienced eye - but I'm not sure.

The fruits seem to be developing OK.. Is this discolouration normal or a
disease ?

Any ideas or advice please ?

Thanks

I grew courgettes last year for the first time. The leaves also turned
powdery white, but this didn't seem to affect the humongous crop... to
my great shame, I ended up putting the last few onto the compost
heap...

So, either it is entirely normal, or in any case it has no negative
effect on the crop.
