Hi all-

New to gardening here... I have spent a bunch of time looking at photos online, but am unsure of what i have going on. I have a few plants in a garden bed (photos with the yellowing) and some in 5 gal pots (photos with spots). Any help anyone can offer would be super helpful.

Looks like mine. Not sure either. Maybe leaf spot fungus. Try Serenade or copper spray and no overhead watering.

Looks like a fungal leaf spot of some sort. Remove diseased foliage, and spray the rest of the plant with a fungicide. Some have good results with Daconil.

Magnesium deficiency. The last pic is something else, looks like mechanical damage.

Agree that it looks like kind of deficiency. What fertilizer are you using?

The last one could be from pests or storms. Or possibly leaf burn, if you've been spraying antifungals or pesticides in the sun.

Still think the first 2 pics are some sort of fungal stuff, typical in summer. The third pic is different, looks like some sort of environ damage.
