Hello!

I’m not very experienced in plants and started to plant cucumber seeds with my son at home as project and they grew up fine! So we took them outdoor and repotted them.

I am trying to read and learn how to take care of them as much as I can.

They just started to produce ! But I’ve been noticing these white stains on the leaves spreading much faster recently, is it something I should be worried about ?

I searched thoroughly on top and under the leaves for insects or spiders but didn’t find.

I end up buying a bug spray for edible plants and sprayed them, just to be cautious.

Any help is appreciated, thanks !!
