Nitrogen or calcium issues?

It’s been a while since my last grow so please excuse the newbie question.

But I can’t figure out if this is nitrogen burn or lack of cal mag.

Now the plant is 7 weeks in to veg, she just started showing signs last week of burn on the tips, yellowing tips, so I went to plain water for this week. Now I’m seeing spots and the yellow tips grew.

I’m thinking I had a calmag issue.

I’m growing in super soil so I wasn’t expecting CalMag issues.

Thoughts, TIA.
