Suddenly sometime on Sunday my peppers and chillies developed white splash looking patches on the leaves, I was away all day on Sunday and worried the weather would be too hot so I sprayed the whole greenhouse (plants & floor) hoping this would keep everything ok until I would get back later that day, it was so hot that day I'm wondering if that's something to do with it...any thoughts?

Sounds like scorch. Probably not done too much damage but keep an eye on them and keep them moist-ish

Sounds like it but don't woory too much,
they are hardier than we think.
