On the fruit or the leaves?

ibarbidahl the spots are on the leaves and getting more every day

It might be root knot nematodes (RKNs). RKNs thrive in our sandy Florida soil and love cucumber roots. If it is RKNs, there's nothing you can do to save this crop and coping with them for future crops is a major battle. You can pull a plant and check the roots for galls -- evidence of RKNs.

hejerry I forgot to mention they are in earthboxes so I do not think nematodes are the problem, but thank you for responding.
