Cucumbers

Question

I have been growing cucumbers indoors using LED lighting. They grew well, flowered and produced good fruit. I still have lots of blossoms and lots of growing fruit at different stages. Lately the leaves have turned brittle and died. I am fairly sure it isn’t water or bugs of any kind. My thoughts are too much or to little light or fertilizer. Any ideas?

Answer 1

What is the soil type that these are growing in? Are the parts that are affected close to the light? It almost looks like sunburn. Not from heat, but intensity. I run LED myself, and this problem is common when they get too close to the light.
