Why do the leaves of my plants have brown spots?

Why do the leaves of my plants have brown spots? I have control over all cultivation parameters except for humidity, which has been difficult for me to control and is currently high. What do you think?

add calmag supplement, watch out for nitrogen, it blocks the absorption of calmag when there's an excess of nitrogen, if you haven't lowered the nitrogen dose yet, consider lowering it before adding calmag, during the flowering stage always consider using low doses of nitrogen, but don't stop supplying it in very low doses.

You yourself understood everything
The reason is either high humidity or high temperature
If you really watched the amount of fertilizer)
In flowering, it is recommended to lower the humidity to less than 50%

Unknown rust on 7th flowering weekThis started as what I thought was a cal/mag deficiency, bought some, gave it for a week at a good dose and 6.3ph, and this intensified and switched from just lower leaves to the upper and a few sugar leaves on one plant. Any ideas? May calmag takes awhile? Or wrong diagnosis?

Dark dots in leaves. Lamp burns?I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.

Brown spots on older fan leavesSpotted 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.

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?7y ago
