Spots On Leaves See Pictures

fox farm nuts, fox farm soil with added perlite, 600w HPS at 80 to 83 degrees . the spots started yesterday at the lower leaves and moved up. watered with the fox farm nuts about a week ago ph was at 6ish. i flushed it today, does anyone know what it could be.

i have never sprayed the leaves with anything

got the same spots so some help would be great. i gathered it was too much N coz my plants went VERY green (DARK) before the spots came

possible micro nute deficiency...... maybe zinc. Im not positive though

Bring your pH up to like 6.5-6.8 your locking out some micro nutrients.

Hydroponics uses a pH low like 5.8 maybe you were confused?

edit: I was thinking Calcium before and I'm pretty sure now...

Calcium gets locked out of soil growing at ph levels of 2.0- 6.4
Calcium is absorbed best in soil at a ph level of 6.5-9.1 (Wouldn’t recommend having a ph of over 7.0 in soil) anything out of the ranges listed will contribute to a
