it seems to be manganese deficiency, it could be caused by too high ph in medium or just lack of it in feed

thought to be sure its manganese and only that it would be easier to identify properly with true colors in the image, you can do that by fixing white balance setting on the camera

and also one larger picture that shows the area of impact on plant. if it is effected on new or old leafs. top, middle or bottom parts. what stems look like and so on, there are many clues to getting it right:)
