Hi, Anyone know what might be causing this? Deficiency, disease, or pest? Thanks.

It looks a bit like the aphid damage I've had, but I can't see any sign of the little sods in your photos. So I'll bow out and hopefully Heefy or another expert will be along to diagnose for you.

Leaves look a bit pale, especially in the second photo. What are you feeding them?

2nd photo the leaf underneath. Looks like the white aphid casings and I agree looks a lot like my aphid damage too

B, Cu, Fe, Mn, Zn

NEKO MERILEVÄUUTE (Seaweed extract)

N 0,25%
P 0,01%
K 0,60%
Fe 61,0 mg/kg
Ca K 0,15%

Mg 0,15%
Cu 0,1 mg/kg
Mn 0,1 mg/kg
Zn 6,8 mg/kg

I've noticed the yellowing (only on new growth) appeared when the fruit was setting. I haven't noticed any aphids on my balcony this year.

I haven't noticed any aphids on my balcony plants this year. The spots you can see is what's left of birch and/or pine pollen. The pollen basically covers everything early on in the year. I've sprayed the plants a few times with water to remove it, but small amounts remain within the water droplets still on the leaf. When in dries, it becomes these little spots.
