my cucumber plants have grown wondefully, giving cucumbers for a few weeks already. in the last few days I have noticed the leaves turned a brown-yellow-golden collor. It looks like stains (not necessarily diffuse), and start to fold inside. It doesn't look good.
I thought maybe they suffer from too much water (hot summer, I watered daily). now I reduced the watering to "every other day" but the plants look the same.
