Mildew on Sweet Peas

What’s the cause, and how can you prevent it or stop it in its tracks? I have been watering the plants every day through the heatwave 😒

They're just dry, and watering once a day in the kind of temps some areas have had isn't actually enough. Sweet peas need huge amounts of food and water to keep them going. They also need good air flow round them, so if there are too many planted closely together, that can have a negative effect.
Bear in mind that a lot of watering can also eliminate food from the plants, so if you have to water a lot, you also have to replace their food, especially if they're in pots.

It probably hasn't been ideal for them this year in many areas.Mine are the same as usual, but we haven't had the longstandinghigh temps that you've had.
I also think it's misleading when people are told to plant sweet peas in full sun. I think they do better with a bit of relief from full sun.

Peas, beans and lettuce all prefer cooler temperatures.
My sweet peas had bad mildew last year for the same reason. I've not grown them this year
