I am not over watering as they just went 1 week without water while I was away, it is not a magnesium deficiency as I watered them with epsom salts last time, and it is not nitrogen as I added a bit of high nitrogen nutes to some water when I fed him last time. He keeps on yellowing! The only thing I can come up with is that it is the PH of the soil, but everyone else is fine in that soil. I am going to buy a PH/moisture probe tomorrow to check it, but what else do you think it could be?

The plant to to the back left of the big plant is also showing the same signs but not as bad.
