Is this a problem?I have some old leaves with a reddish tint around the leaves, couldn't find any nutrient deficiency/excess that matches, maybe phosphorus?

Brown spots, PH in run-off is in the high end (6.5~)I see some brown spots on my leaves. I thought it was Calcium Deficiency caused by too low PH so I gave them PH 6.5~ with 30% run-off, and run-off shows at least the same PH so I think it is not too low PH, could it be caused by something else? Maybe too high PH or light-stress?

I think my plants are suffering a Phosphorus deficiency due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad

Lack of light or Cal-mag?Some spotty leaves here at the base of the plant. The overall plant heath is fantastic and dense, haven’t done much defoliation so the bottom gets very little light. Is this a no light issue or calmag? I’m leaning towards calmag but the lower canopy gets very little. Advise?

Which pests do this?Exactly what pest does this kinda damage? I have my guess, but wanna get other growers' opinion on this type of yellowing of leaves and brown spots. 6 weeks into veg. It started very early on at bottom leaves, once I trimmed them this brown spots appeared on top growth.

Brown Patches on Older LeavesSlight yellowing and brown mottled patches.
Only on one of the two plants and they’ve been treated and fed exactly the same.
On some older fan leaves, no signs of anything on new growth.
Anything to worry about at this stage? Maybe just a sensitive pheno?
Any advice appreciated.

Rusty Leaves3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera.
I also have slight "clawing" on many of the upper leaves.
Mg/Ca lockout because of nitrogen toxicity possible?
Doesn´t seem to be fungi, as there are no spores to rub off.

Was haben meine Pflanzen?Dear community,
Newbie here :)
I have two Critical Kush Autos in their 7th week that have had slight necrosis/discolored leaves since flowering.
Unfortunately, I only fertilized for the first time with Hesi Bloom 5ml/L three days ago, not at all before that.
More nutrients? Less light?
