When to pick cucumbers?

We're into Spring here in Australia Getting up to 30'C (86'F) this week.
You're right, there was a new flower today so I think it's still good! It looks healthy, but I'm sure I'd be more productive if it were in the ground instead of a pot. I live in a unit with no garden though, so this is the best I can do.

I think fertilizing with tomato fertilizer could help, and if you expect humid weather which promotes fungal disease, start spraying the plant with milk solution to ward off the fungal issues. When there is no sign of powdery mildew yet, you can just use the 10% solution I believe, though I would increase concentration if any hint of white spots or yellowing is present. Thoroughly wet both top and bottom of the leaves.

Good to know, thanks I have never seen powdery mildew on any of my plants, but I will keep an eye out as it gets humid.
Cuc #2 is growing well, but once again all flowers and baby cucs have stopped. Funny how this plant only wants to grow one at a time.
