Calmag issue in mid flower?

I looked at your diary and I see that you’re in Coco coir which is basically a soilless medium. I use Lotus Nutrients and myself also being in a soilless mix of Peat/coco/perlite. The Lotus “Coco” chart recommendations are to supplement cal mag up until week 7 of flower or up until the second last week of flower depending on the length of time a specific strain takes to flower. So my answer to you for your specific set up is that absolutely you should be giving cal mag throughout the flowering cycle. I hope that helps you bro. Good luck 🤙
