She wants more potassium and phosphorus and less nitrogen in her diet.

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 🙏💚

VPD related leaf issue? Brown spots, don't think its Cal related. Pls, any help would be appreicated.
Brown spots on leaves, I thought it was Cal related, and tried different doses, with no success. Could it be VPD related? It can and does get very hot and very humid in the 1.5ftx2.5ft closet. Even when running no humidifier (Live in AZ). I've been struggling with this for months

Cal-mag issue that won't go away
I keep getting a cal-mag deficiency. I have been using 1ml per liter of water - 4ml roughly per gallon. It is only 1 plant, the same which has had the same cal-mag issue since early veg. I include cal-mag every watering and nutrient feed day. You can see images for reference

Flushing don't seem to solve my lockout
It's been 6 days since I noticed the problem. first thought it was a deficiency but really is a lockout. I flushed 2 days ago but she keeps getting worse. Am I being impatient? I flushed with tap water pH 6-7 until the runoff was in the same range and haven't fed her for 4 day.

Yellow/Brown/Spotted/Crispy Lower Leaves
What is wrong here? Gave an extra dose of nutes but the problem only seems to be getting worse and spreading up the plant. Definitely effecting the bottom leaves more. Others said to just increase N-P-K ration, but this seems like something specific.

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 am seeing an issue with the lower fan leaves and it seems to be progressing upwards. The leaves are yellowing and also seem to be turning brownish. I added CalMag into my last feeding but beyond that not sure what I should consider, info/advice is appreciated. See last pic wk5.
