Could be easily be a calcium deficiency, as well as an out-of-balance pH. You seemed to have fed plants heavily also.
Other than that, it can just be a bad plant. It can happen at times. You can expect that even when working with clones.
It looks like temps and humidity are quite high too, given you're in 5th week of flowering.

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.Older leaves have brown/red rusty spots and looks like dying tissue in between the veins.
Burnt tips, and yellowing leaves.
The soil was really dry and my PH meter was 0.4 too high.
I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff.
Runoff was PH: 6.1 EC: 0.8a year ago

Overfed P and KUnfortunately i have overfed PK as thought the bottle said 7ml per L but instead was 0.7ml. Noticed tips of leaves the next day browning so checked the feed chart again and pretty much shit myself. Flushed all 3 plants for about 5 mins and now they seem ok hopefully.Week 8

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?Leaves. Color - Yellow
