Hello,

I have some courgettes in a cold greenhouse that I have grown from seed.
The greenhouse is ventilated in the day, and closed at night.

They seem to be growing OK, new leaves coming on etc, but the leaves seem to be looking a bit worse for wear ... see the photo which explains better than I can !

Thanks for any help,
Ben

  Do they all look like that?

And really,don't put slug pellets in a pot.

[ben]

They do all look like that
As for the slug pellets, they just fell in when I sprinkled ... didn't see any harm in them being there ... is there ?

Have they got scorched in bright sunlight?

I agree with sunshine band, looks like sun scorching.

I have been known to use slug pellets outdoors in pots in my back yard as the slugs there have huuuuge teeth

they look hungry and dry too 
i like slug pellets too ,what harm they doing in the pot gobby ??

[ben]

I only ever water them at night so that the leaves don't get scorched ... is it possible to get scorched even though there are no water droplets on the leaves ?

With courgettes, like squash and cucumber, you really need to avoid water on the leaves as they are likely to rot - perhaps that is what has happened.  For mature plants it is best to have a submerged bottle to water through and under the roots, for smaller ones aim to water the soil rather than the leaves.  Also avoiding too much water on the stem (so water slowly!)

Yes if the sun is very strong through the glass  Anything can fry like that

capillary matting can be very usefull or an old carpet

My understanding about slug pellets is that you want to entice them out of a place with it. So, only want to put on the furthest perimeters you can.

I don't think it's scorching, especially if all plants look the same and also, emerging leaves look like that. Have a look into this next rainy day.

I used sheets of newspaper this year before I got the shading up. Still put it over potted on seedlings to give 'em a bit of a break on day one 

[ben]

Thanks for the replies, I'll try to not water over the leaves and look into some shading.

I shall consult me clever book, Ben on one of these rainy days, they don't look much promising. It could be sun burn, but every single leaf on all plants, hm?
