Mildew on cucumbers

I’ve got 4 cucumber plants growing outdoors up a bamboo trellis. 2 mini cucumber and 2 regular, lost the labels so can’t tell you varieties.

The mini cucumbers have been great, looking really healthy and we’re picking 3 or 4 cucumbers every other day.

The regular size plants have been ok, we’ve had a few nice sized cucumbers from each, but they’ve been affected by powdery mildew. 

So far I’ve been keeping it at bay, cutting back the affected leaves and spraying with bicarbonate of soda solution, but I’m starting to loose the battle. The bottom of the vines are now totally bald, but they’re still growing and producing flowers and a few cucumbers at the top.

I’d appreciate some advice from the hive. Do I keep going and try to get a few more
cucumbers. Or do I cut my loses and pull them up before the mildew spreads to the mini-cucumbers?

Thanks in advance.

Sorry about the photo. Didn’t manage to get out before it got dark.

    Well Womble this happens a lot. Make sure all water is at roots and not on the leaves. It looks ok at the top and I see baby ones so keep going. The season has only really just got started so if you can, keep going. If you want, now the leaves are out of the way, you could underplant with something like lettuce, radish or spring onions ,all only take a few weeks to be ready. Just a thought.
