I've posted four photos at the site below (let me know if the link
doesn't work).

The first two are Bell pepper plants that have a yellow-lime green
discolouration on the outer part of the leaf. The third pic is the
cucumber that has some white spots and the celery in the fourth pic also
has some white spots (powdery mildew?). This is my first time growing
these plants. Just curious if these are normal or cause for concern.

I've used a little potato dust on the pepper (and tomatoes in the same
greenhouse) cause it has been humid. I used a baking soda/water solution
on the celery and cucumber.

White stuff on cucumbers and celery doesn/t look like powdery mildew to me.
My first inclination is to rub it off with a finger and see what happens.

The pepper looks like it has a nutrient problem evidenced by the green veins
and is more serious. I might try a foliar feeding and hope for the best.

Thanks...I'll try that.

It almost looks a bit like sunburn to me. (It didn't look to me like the
very newest leaves were that distorted, but you were favoring the older
leaves in the pics, so I'm not sure that impression is correct.) Did they
ever get very wilted before being watered?

I'd give the plants a nice foliar feed with kelp and keep my eye on them.
Avoid touching the effected plants (on the off chance that this is a virus
disease which you could then spread to other plants).

cucumber that has some white spots and the celery in the fourth pic also

It looks more like the remains of a watery bird dropping. Does the
white stuff wash off? (It certainly doesn't look like mildew.)

I took a closer look today and it was the older leaves that are
yellowing. The most recent leaves on top are still quite green. The
plants are in a greenhouse and we've had some nice weather, so the
sunburn explanation certainly fits. It's been cloudy since those top
leaves came out and they're fine. I'll rig up a bit of shade cloth for
them. I've also given them a foliar feeding just in case.

The stuff does rub off. I'll check back later today to see if it
reappeared. They're also in a greenhouse so it's definitely not bird
do-do (but does look like it). The plants seem healthy except for a bit
of curling on some of the leaves, so I'll not worry for now.

Thanks for the suggestions.

I'd put money on it being a bird dropping - it's definitely not mildew.

The first picture of the pepper leaf looks a lot like early spit!
thrip damage. The up curling leaf edges make me suspecious. The
second looks more like sunburn, though.

I hope for your sake it's the sunburn.
