I have 8 plants running outdoors right now. I am feeding 3X’s a week with the humbolts starter pack. I am getting a lot of yellowing on my fan leaves. Buds look healthy and are swelling. Should I be worried?

Yellow leaves
Hi guys, unfortunately because of an emergency I had to leave my 2 babys with some friends for three weeks. At the bottom some yellow leaves and like burning signs. I don't think it's because of over nutrition. They didn't get any for three weeks. Might be not enough nutrient?

Rusty Leaves
3 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.

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?

Yellowing of leaves during flower
What is causing yellowing of the bottom/backside fan leaves during week 5 of flower? Should I worry about it spreading? Increased bloom nutrients to 3ml/l recently but could have started when feeding 2ml/l. Or is this just leaves yellowing as a part of flowering?
