Cucumber leaf wilting and spotting

Asked May 20, 2020, 7:07 PM EDT

Several cucumbers we recently hardened off are beginning to show significant damage on the cotyledons and some yellow spotting on true leaves. What is the cause of this? If it's fungal or bacterial, are there organic controls?

Thank you for your question. There are many causes of yellowing. Could you please share how much water it is getting, whether and how much you’ve fertilized it, and how much sun it gets (when there is any)? Thank you.

The plants received no fertilizer prior to showing symptoms. However, they have been outdoors and unsheltered for the past few weeks with steady rain (roughly an inch and a half over the course of a few weeks).

Your plants need fertilizer. They are ‘starving.’ Add organic or time release fertilizer ASAP.
