Sorry dude I was supposed to reply but been super busy. Some nutrients are actually designed for soft water obviously not RO and your in soil so it could build up over time if not used. Also the if there cutting calmag that early I'd assume they are aiming for a week 8 harvest.
If was me I would continue week5 for a couple more weeks then resume their schedule putting you on a week 10 finish.
Completely cutting c-mag won't hurt so late imo. It can be corrected quickly if deficiency shows early but not massive problem so late too.
Oh and plants looking a straight 10
