Downy Mildew of Cucurbits - Cucumber

Kratky hydroponics. I got this diva cucumber as a sapling from a garden store, it's been growing really well and fast, but now the lower leaves are having problems. Also, two embryonic cucumbers just turned brown and never grew, so I cut them off, now it seems like that might be happening again. Aren't diva cucumbers supposed to not be polinated? Why aren't the cucumbers developing? I just changed out the nutrients today with a mixture for blooming/fruiting since I'm assuming it's a nutrient deficiency. The new pH is around 5.

Brown leaves, veining, not fruiting
