PH 6.5 is only for soil. Soilless mix needs a slightly lower PH in the range of 5.8 and 6.0

The inter veinal discoloration could be a few things. My first thought would be it’s light related. If not, I’d look at N & Mg

Light stress was also my first thought. The lower leaves have discoloration from it as well. Those are more sploched and bleached looking. I've seen the same on some of my plants.

Probably Mg (definitely not Ca, no rust spots) and it needs 6.0 for good uptake. Also have you been spraying them with something, hopefully that isn't PM.

Add some Calmag @ 5ml/gal to your water. Thanks for sharing PH that saved time. https://www.amazon.com/Botanicare-CAL-MAG-Plant-Supplement-Formula/dp/B004JKBMRW

I second this. Either way he'll likely need to use a cal supplement to get Mg unless he wants to use epsom salts or something. Thats definitely spray residue. I've had battles with PM for years.Dx
