Well it does look like calcium but not magnesium.

If you tell us more about your grow then we can perhaps point you towards corrective action.

Stuff like, medium, feed mix / ppm / pH, water source / ppm / pH.

I'm using all mixed from the bio bizz range, in week 5 of flowering, my PH is around 6.2/6.5 when adding nutrients then applying it to the plants /top -max bio-bloom bio- grow. Appreciate the reply cheers

Are you using RO or distilled water or tap water? Purified water lacks calcium.
