I've got the same yellowing plant issue again with 3 autopots, today I got them to the front to give me access to them for hand feeding.
Ec and ph are good so it doesn't leave a whole lot?

I tested calmag on one plant (front right) and lol, well you see it lol.
The issue doesn't show up great in that pic.
Cheese dipz it's getting worse day on day?

I need to go back to the drawing board with the autopots?
@conor c is it within the realms of possible they're too wet with 50/50 coco and perlite?
Does that plant at the top look like what you'd see with too wet?
Cheers bud
