what’s the problem?

Not a lot of info to go on but with the yellowing appearing to be only on the upper leaves I would guess either too much/too close to light, or a ph issue.

Yea, give us a little more info mang! I think I saw your thread but, what are you growing in? Nute line? pH? etc..
First glance: Mag def? Add some plain epsom salt, 1g/gal. It’s just MG and Sulfur. It won’t throw other things out of balance like Cal/Mag. If the Mg is low adding more Ca won’t help.
This might not be the problem depending on the other stuff. This is a nice “too much this causes too little that” image. I saved it from @Man-O-Green
