Venkat Pawar. This morning only 3 leaves were affected. Now in the afternoon almost all of them. They received a potassium focused fertilizer Every two weeks

Venkat Pawar. If it is potassium deficiency, I don't know how to Treat it, as they already get lots of potassium.

Victor I assumed Potassium Deficiency due to burning of leaf margins but after checking current pics I think it might be the case of Water EC. I suggest you to check EC and PH of Water.

Venkat Pawar. The water ph is around 6.6 - the soil is at around 4.5. I will add some calcium to bring it up to at least 5.5. But that can't be the problem, can it?
