Fungus or deficiency?
I have these gals growing outdoors and have a few leaves that look like this. Appeared after multiple heavy rain days. Applied nutrients yesterday so I still need to wait for the results. Is this a sign of fungus or deficiency?

I water with 50% distilled and 50% rain OR 50% distilled and 50% tap. I have fed once with Grow Big and it happened right after. Might have rubbed nozzle on the underside of the leaves. I water every 2-3 days and water until drop of runoff appears in tray. How much runoff?

Many or low nutrients?
Hello Growers What could it be? I thought it would be a nutrient deficiency (EC-1.0) so I picked up the nutrients to EC-1.4, but it's getting worse. Do you think they'd have a lot of nutrients?

Copper spots
I noticed these copper spots and leaf tips about a week ago, it doesn’t seem to be progressing too fast. The plants otherwise seem to be healthy but what is the issue? Magnesium Def?

Leaf spots!
Leaf septoria or nute deficiency? Don't have ability to monitor pH or ppm. Do I cut the affected leaves off or any other home brew solution? 3 different plants in the photos.

Spots on leaves
Anyone know what's causing this? Slight discoloration and rust spots, mainly on older leaves. It's not that bad but quite spread out. did spray with neem oil recently, so is it just burn spots or a nutrient problem?
