Hi again Moses

Maybe you should list some more info ?

Like naming the cultivar, does it happen in both beds (Led/sunlight) and to all plants ?  do the different, beds receive the same water/nutrition/light-hours/temperatures  etc.

The more details you provide, the bigger likelihood someone will pinpoint your problem.

cheers

Its a pak choi but i dont know what varieties this is, its grown with LED and yes both sun light and led receive the same nutrition with only the difference being the amount of fish, all water parameters is ok. cant really measure the amount of light received, since i do not have PAR meter and Lux meter. Temp of water is the same for both. daytime growbed on outside is considerably hotter while at night time the indoor LED is a little bit warmer.

Which aquaponics technique do you follow?  Diagnosing a nutritional problem is not an easy thing to do without knowing it.

I'm not a disease expert.

Have you considered it might be this. 

White rust

What is your pH.  I've found high pH to cause all kinds of problems.

 that is a blister rust, it should be powdery right? yet mine is not powdery at all, i notice the pigmentation of the leaves change to these color, some people suggest it might be sunburn / frost damage, which i think it might be sunburn. maybe 14 hour on the LED is too much after the leaves has fully grown.

I had problems with my LED grow-light burning the leaves of my plants, but I had gone from 12 hours light to 24 hours of light and the plants had grown up and were within 18" of the light.  I raised the light higher and that stopped the burning.

probably this is what i need to try since the vegetable is not being eaten and it kept growing bigger and taller
