What is she trying to tell me ?
Could anyone tell me why some leaves of my orange sherbet are dying ? Is it stress (the plant is in front of the fan) or cal-mag-potassium deficiency (I don’t have neither cal mag or potassium). Thanks a lot 🙏💚

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?

Nutrient lockout, ph imbalance or nutrient burn?
Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn. The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.

Any suggestions on what you think the problem could be with #2 could be welcomed. Air pots, soil dries out 2-3 days, temps stay in same range, since sick no training was done, brown spots starting at old growth and moves up plant on big fan leaves 1st then rusty look as progress?

I believe I have a phosphorus deficiency from lack of watering/early pH issues. I also have curly/dented leaves that can be seen in the close ups. Does this seem like a phosphorus deficiency or what else may it be?

I wanted to ask if you think this plant has mold or if it's just a major deficiency due to a blockage. I have an indoor plant next door with some plants growing with dark spots, it's in my previous question. Sorry for giving more information, I don't know what would help.

Damaged leaves
I have a problem with one of the plants, the leaves are damaged and some of them had to be removed, the plant is growing too slow. I thought it is related to Cal/Mag but I've been adding it for a while since week 2 and the problem is not corrected
