Actually been a poor growing year, my chillies were rubbish too.
That mirrors our 2023 summer here in the UK, both my hops and chillies were poor. In fact, I've been growing chillis for almost 20 years and there was just no heat in any of them last summer, I guess it was the lack of sunlight: was warm enough, just cloudy nearly every day. 2024 seems to be going the same way
