Hard to tell, but the dark veins on the leaves looks more like a Mg issue (but it could just be the lighting/shadows in the photo). From the burnt tips I’d say you have enough NPK. Other than the one leaf, I’m not seeing much lower leaf yellowing. Again, hard to tell in a picture, but maybe a little too much water, are you letting the pots get light before watering?

Got some calmag if u think that would help? I’ve got 2 and this one is the only one showing problems, the veins do seem darker on this one. Maybe a little much tbh normally stick my finger in the soil a bit down feel if it’s damp or not

It’s really not showing Ca issues, you might try a foliar spray of epsom salt, google the recipe. You’ll see very quick improvement if it’s Mg.
