I'd say there blotches on those leaves, mate.. get it sorted before it ruins a nice crop.

Could you give a few more details like medium used, lighting, nutes ect. it would help in finding out what the problem is with your plants.
Sorry for being flippant earlier..! ..

I use 3 part gh. 600 watt light. Aero tub always on. Up to 1050ppm. Just added some hydroguard a couple days ago.

Why? Why do I need to add stuff when I'm using 3 part gh nutes? ?

I would lean more towards a ph issue. Calcium would be more spotty.

Calcium issue

Ph issue

IMHO, ph or nutrient splash, apart from that they look like fine plants, well done mate.

I think maybe splash. Here's why...
They are in a homemade aero tub so the wholes aren't tight.

Only the bottom leaves that are close to the lid seem to be affected.

So if I had a deficiency or ph issue it would affect the whole plant right?

Ph is at 6.2 and has been between 5.9 and 6.4

Deficiencies can affect some parts of the plant first before it hits @ other places, like lower leaves progressing upwards & vice versa ect.
Have a look at this and see if it's of any help.
