My plant (Exodus cheese) has been recovering from a nutrient deficiency but I noticed the leaves are turning brown in the middle. Why is this happening?

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)
I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

Leaves browning in multiple spots Lower leaves yellowing but have green veins.
One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?

Some brown spots showing on the top sugar leaves. I suspect it is due to the cooling fan of the light blowing down hot air? I've adjusted the fans to blow air directly over the top of the main cola's and I increased the light distance.

Is this really a potassium defiency? Any suggestions how to deal with it?
Hey Guys, need your help please. It's FD 28 and the leaves of my three White Widows show some signs of a nutrient deficiency (at least my assumption).I'm growing in living soil w/o any additional fertilizer and watering with a 7:3 mix of osmose/tap water and 0,5 ml/l CalMag.

Bruciatura da luce o fertilizzante ? (Dwc)
HELP! I would like to solve and find a valid explanation for these leaves that are burning, mainly on the main stem, which is the most exposed to light." I have also added a dose of nutrients since it is the last week of bloom. Does anyone have any idea💡? Thank you

Brown spots on some leaves
Hi guys, today I found these spots on some leaves, few actually. I think it is an excess, in fact the EC in my DWC has been rising for a few days. Could you tell me more please? 😑

Spots on leaves and little twisted...
Spots started slowly showing when it had a different 600w light, too much heat back then, this started a little "save operation" changed light, made the plants look a bit healthier but now it looks like the spots have spread and also affected the leaves above... Are they healthy?

Hello fellow experienced growers, is what I see on this leaf, combined with a reddening of leaf and main stems really signs of a CalMag deficency? Or do I have another problem? And is 1 ml CalMag Agent enough to counter it? Dont wanna risk anything so close to the goal...

Aeroponics system; fan leaves start browning on edge in 2nd week of bloom.
Aeroponics system that my fan leaves start browning on edge in 2nd week of bloom every time (about 7 grows in journey). Is this normal? Should i be concerned and adjust nutes at all? Or just selective trim any of the more "crispy" ones? Photo is 2nd-3rd week into bloom.

Do these look healthy? Thoughts? I'm new to hydro/growing
I have autos growing in a dwc system being fed half the regular amount of hydroguard, calmag, and grow/bloom. 1 plant is a week younger. The dark green plant looks like its leaves are clawing and has big brown spots on the leaves. The other has some brown dots and little yellow.
