Magnesium deficiency. Either correct the pH a bit towards 6, so it can be absorbed a bit better or you buy a calmag product (i would highly recommend, i always use it) and it will fix itself. The problem will take a while to get fixed since you grow organic. necrotic spots will stay that and not recover tho Or maybe if you run really low on fertilizer, and give a bit more, goood luck
