Looks like you need nitrogen and cal mag. What are you feeding? The brown spot looks like pest damage to me.
I was a week late on my compost tea as well as my weekly application of dr zymes. So could honestly be both... didnt think it would get to so many leaves so quick. What kinda pest you think I was struggling with mites a while back but they were gone months ago, or at least couldn't repopulate.
Im not a pest expert. That just looks like pest damage. Thrips would be what I would be looking for. Check with a microscope along trunk where branches meet and underneath leaves and along stems. Their hard to spot with the naked eye.
Looks more like something that outright munches the leaf and leaves the top skin intact! It looks more like caterpillar, beetle or larvae damage of some sort... That's going from those vainy dark blotches and what looks like something ploughed a line across the leaf! Start checking underside of your leaves and any nooks and crannies, see if there is anything that shouldn't be there. Snoochie Boochies!
