A couple days ago I found some translucent/gray patches on some of the leaves of my tomato plants I planted at the end of March. The plants haven't blossomed yet and there's been very little sun with high humidity plus a lot of rain recently but when I saw these patches I thought it better to just take the affected leaves and stems off as it seemed like it was spreading across the plants. Does anyone know what the cause is? Should I treat them with something?

Thanks for any help! First time tomato grower hoping they will survive 🤞🏻
