Hello, I am growing 2 sweet slice cucumber plants that I started from transplants bought at Valley View farms. The plants are in a container and I have used brand new Espoma potting mix. I mulched with pine bark. I have harvested one fruit from the plant. The leaves however are starting to turn yellow with brown spots. The bottom leaves on both plants are affected the most. Although there are male flowers and one healthy fruit on the plant, the ovaries of female flowers and tips of some of the tendrils are drying up.

I have given the plants Espoma liquid fertilizer (organic) and while planting, I added some organic fertilizer in the soil (Tomato Tone). Please see pictures and please help me identify and address the problem. Thank you very much!
