Calcium deficiency use calcium magnesium. Could be boron but that usually has twisted leaves and starts at the tips and is rare

Brown spots on older fan leaves
Spotted some brown spots on 2 of the older fan leaves today. Any thoughts on what the issue may be? Does not rub off- was worried about rust at first. Some more info that could be helpful is that I am using RO water. Thinking about rasing the lights a little higher up too.

Dark green leaves in meringue
Is my girl telling me that the flowering fertilizer is too nitrogen loaded? I´m using top bloom from top crop, feeding at 1.4-1.6 Ec, and since last week I started to follow the feed-water-water schedule. The NPK of this fertilizer is 4-8-8. Should I adjust the input EC?

What deficiency is this ?
What is happening to my plant right now ? I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks. Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil. Started around 6th week
