What has happened to my Japanese Cucumber plant

[polaricdawn]

Hi there,

After much reading on Aquaponics on this forum and other websites, I have setup a mini indoor system for about a month plus, growing japanese cucumber, chilli, butterhead lettuce and parsley plants. I have added iron/potassium supplements on a weekly basis into the system, however I notice discolouration on the japanese cucumber leaves (see photos attached), the discoloured portion is almost translucent/see through.

Can anyone kindly enlighten me what nutrient(s) are deficient?

Thanks.

Maybe this may help?

Not sure... i would've gone with some kind of leaf mining insect to start with...so maybe leaf mining bacteria isn't too far from the mark?
