Is this a Cal deficiency on fan leaf?

Hey all, just getting confirmation on this, I see leaf discoloration with this strain from week 4 on. Gets increasingly worse through bloom. Happens on the fan leaves getting the most light. I figured it was a cal deficiency potentially locking out nutes, not allowing the leaf to do its thing with the heavy light load. Using fox farms OF and just GH MaxiBloom. The girl is supposedly a sour diesel x tangie, takes around 9 weeks flower. Thoughts? Probably need to get cal mag and/or g. Lime.

How would you correct this? Thx!
