Few questions

Have you checked for bugs ?

What nutrients u using ?

Personal opinion straight of the bat. Looks like thrips or leaf miners to me
 
No bugs.. I have a lonley ladybird. I'm using 50%tap water/50%distilled.. professor nutrients.. for it to be that far gone there would have to be heaps of them
 
First it was mag.. I read that wen u fix 1 , the other one can go out.. so I'm Gona have to bite the bullet and get some calmag I think..

Have a look at the leaf below, you can see the lighter color between the dark veins. Definitely a magnesium deficieny in there. Could need cal mag!? Could foliar spray with epsom salt and water mixture as a bit of a kickstart to adding cal/mag to your res??
