What deficiency does this look like?

What deficiency does this look like? I’m using cal-mag with a 5.5ph to 6.5 ph. The older fan leaves are having this problem on two of my plants.

Thats too big of jump in ph if you’re in soil keep it at 6.5. Save these to help with future issues.

I changed the Ph because it originally had a phosphorus deficiency which occurs when the PH is too low. That seemed to get rid of the spotting but the yellowing still hasn’t stopped so I’m thinking it’s either a manganese, magnesium or zinc issue. It’s so hard to tell by looking at the charts.

Looks like magnesium
