Greetings ! Help please leaf issue

Hi ILGM fam !!!
First time grower, having a little leaf issue ive done some research based on images and from what ive seen it could be a potential Cal/Mag issue.

Can anyone advise ?

Did you rinse and buffer your coco with cal mag? Coco needs to be rebuffed before using. You rinse it in PHd cal mag at 300-400 ppm until your runoff matches. Some folks just soak it in cal mag solution. Your deficiency looks like beginning calcium deficiency , don’t see any magnesium yet.
