Spots on leaves

It looks like a minor calcium deficiency. A bit of Cal-Mag will sort it. Biobizz do their own one if you want to keep using their brand.

They are only on one of the plants, they have gotten a spray with Dr. Zymes Eliminator and had no effect, also did a mL of Cal Mag in its last water with no effect and getting worse.
