Kinda looks like calcium

I'm growing in coco

Calcium deficiency IMO. It's a common thing in coco, sometimes due to a very low pH. What water do you use?

Calcium dont worry aboutit this late in the grow, your almost at the point to taper off with calmag anyway. Probably want to pick some up for the next grow forsure and if your not adding it to this grow i bet the next grow makes wayy better flowers. I dont add calmag for the last week and a half of flower and since your at six, Whaterver.

I have calmag but I wasn't really using it because I was using sensi bloom coco nutes but I guess it wasn't enough calmag in it

We cracked the case good to hear.

I'll definitely agree its a calcium deficiency but to terry385 point those white spots/speckles seem like some bug damage. Calcium for sure. Also take your loupe and look on the underside of your leaves for bugs. Good luck.

Calcium dont worry about it this late in the grow.
