blight?

[Acanthus]

This has occurred today: in 2 different greenhouses, different appearances. On one, the plant seems to have just given up and started to wilt, in spite of having plenty of water. They were fed 2 days ago. In the other, dark patches are appearing around the leaves, within the leaves. They are quite hard, almost crispy









What do you think?

I am really worried about these, don't want to have to burn them

My gut feeling is that that is sun scorch-although it's a bit difficult to see thelast couple of piccies. What have the temperatures been like in the greenhouses??

Did you feed more than the plant thats wilting?

Sorry but the third one looks and sounds like blight.

I would wait until someone with more experience of blight comes along before taking any action

Blight isn't crispy is it???

blight leaves soft black sooty looking patches on leaves and on the joints of the stem. Most of yours sounds like good old scorch.

The weather has been so changeable, one minute it's pouring with rain, and they don't seem to need any water, and the next day it's really hot and I water twice a day. They all got tomorite 2 days ago. It's been up to 30degrees sometimes in the poly. I'm keeping vents and doors open all day, just closing up at night.
