Please look at the leaves shown, orange and dried parts. I asked a similar question earlier but these look more damaged and I'm wondering if it's worsened due to my setup. Wind damage from fans? Water damage from humidifier? Light or heat damage? Managing VPD is tough. Thanks!

Calcium Deficiency Won’t Go Away DWC
So plant #1 is still having some Calcium deficiency issues. I’m using RO water and giving the recommended dose of CaliMagic which is 1tsp(5ml)/gal. I’m in DWC and using LED full spectrum lighting. Why can’t I stop these spots? Should I give more than recommended dose of CaliMagic

Brown spots on bud site leaves?!
halfway through flower and now in week 6 flower one of my plants is showing some large brown spots on only the upper leaves. I’m not sure if it’s a light or ph issue as the light is close. I stopped cal mag and some nitrogen this week but spots were showing up before.

What does she need?
She looks like she's over or under watered. Now this seems weird to be because she did this over night a day ago. I water her just as my others and they all are great. The strain..Chempie, by ripper seeds Tested the soil out, doesn't seem to be on to dry or wet.

Rust spots on leaves
Check the pics and recommend something to help a newbie out. I’ve seen it for a couple weeks. I removed all leaves with necrosis, but it came back. I don’t know for certain what it is. I think it might be a calcium deficiency. I was going to go out and get some gypsum, but I want

Spots on yellowing leaves
Brown spots on dying yellow leaves. This has happened on most of my plants after budding so thinking it may be a soil problem. My guess is boron, manganese or phosphorus as the stems on some plants are red. It starts low and eventually ends affecting buds too so I chop.

Clawing and Brown Edges
Got some major clawing and brown edge action here. Anyone seen this before? I'm in FFOF with 20% EWC and 20% perlite...not really convinced this is nute burn, even though it looks like it...leaning more toward light/heat burn. Using the SF2000 and had it at 60% roughly 20in above

Is this bud rot?
I found strange purple/dark brow discoloration on one of buds and surrounding leaves. It could be caused by bad supercropp of the cola, or I am thinking bud rot. What do you think, should I harvest immediately, or am I stressing too much? RH is 50-60%, but the box is cramped.
