Dying Cucumber Leaves…

Dying Cucumber Leaves…

Our cucumbers (Lemon Cucumber and Yellow Submarine Cucumber) have been producing fruits, but are slowing down in production. I noticed that many of the bottom leaves have dried up and turned brown. Is this normal? or is there something wrong?... and if so, is there something I could do? I side dressed with a little 4-5-3 natural tomato and vegetable fertilizer about a month ago.
