Is this Calcium or Magnesium deficiency?

  1. This has slowly developed on the lower set of leaves. This is a 12-day old White LSD Autoflower. pH always maintained at 6.5 have not added any nutes yet or CalMag. Any ideas on what to do? It's not on the new leaves only the older ones at the bottom.

  2. Could you take a pic with neutral lighting
  3. I figured it out it was from me using distilled non-pH water during germination. That explains the damage on the older leaves and the newer ones are fine.
