Yellowing edges and brown tips in 7 week of flower.
Hello, fellow growers. Need some help. I'm in 7th week of flowering and upper leaves start yellow with burnt edges. The lamp was too close(30 cm) for 3 days. I raised it to 50 cm ten days ago, but the symptoms are stil progressing. Is it light burn or potassium deficiency?

Überdüngung oder Mangel ?
Bei all meinen Pflanzen bilden sich gelbe Blattspitzen aus die auch etwas verbrannt aussehen. Denke nicht das an der Lampe liegt, die ist 70cm entfernt und läuft auf 50%. Wachsen auf Kokus und Lightmix Erde von Biobizz. Gedüngt wird mit Biobizz nach Düngechema.

Help! Sick looking plant
Hey! My plant has been looking really weak for the past 3 days. Can't figure out if it's a PH problem or a nitrogen deficiency. Any tips? Thanks 🙌

Some tips are bit burned. Does my nutrients amounts are too high? I cant tell, not much references on aero garden nutrition schedule. 1. Should I reduce nutrients? 2. Barely seen growers using CALiMagic - do you think I should keep it? 3. Any general tips? :)

I probably have spider mites on my plant. Yesterday I sprayed it with Maag oil. Today I bought an organic product and sprayed it on the plant. Are the discolourations on the plant caused by the mites or burns due to increased light from the drops? Or a lack of nutrients?

Sick leaves, good buds
Some leaves look sick. (Last photos at 8 weeks) Is this an overdose? Do I need to fix this? From fertilizers, I apply only ripen. I plan to give it 2-3 times and then flush and harvest. I know that ripen helps to end life and makes the leaves turn yellow, but not so!

Why do several of my leaves look like this ?
I be had quite a few leaves that look like this , I’ve taken them off the plant because I’m not sure what it is. Do you all know? I just want to make sure I’m not experiencing pests or mold.

Discoloration and Spots
I'm still not sure if this is a deficiency or some sort of burn. It's definitely spreading a bit more, and I'm unsure if there's time left to address it in the grow. Video of full plant in week.
