I thought I was having a bug issue but am now thinking maybe disease but kinda panicking because I should be flowering soon. Some advise would be greatly appreciated. Please take a look
Septoria or bug???

Some of those with holes in the center of the brown look like leafhoppers, but others not so much. I would start with a microscope and look for bugs. Check the stacks, too, sometimes they are easier to see there. Wis I could help more.

Im starting to think everything is bug related...my plants just sit out there...nothing happens...sun goes from east to west for a few months and the plants are cut down. There's nothing out there but bugs!...right? Im stumped too dude. We need leaf analysis field kits or something

One of my plants had a couple of leafs with similar spots. I would like to know what that are. I'll look the charts over and see if I can find it.

The insect responsible for this damage is the potato leaf hopper (PLH). It is a tiny, bright yellow-green insect that feeds on the mid-vein of the leaf causing the characteristic “v” shaped yellowing at the tips of leaflets. Hopper burn is NOT caused by three cornered alfalfa hopper.
Fk yeah i think DC cracked this old mystery
Alfalfa hopper...i have hundreds they dont do anything.
PLH these fkrs are beautiful but these are the culprits according to DC , i also have many of these...and im highly in agreement

They have all types of crap they carry, incuding a few viruses and phytoplasmas.
I had BLTVA, aka purple top, once on a plant. Growing end turned puple and dudded, weird as hell.

That's kind of what I think. I've never thought about them killing the plant edges before even after seeing it. It's hard a associate two different looking symtoms.I think "Leafhopper burn" looks similar on hops, potatoes, grapes.
The area they feed on dies from whatever pathogen they carry, then it travels thru vascular system and kills the edges.

You're using Daconil on cannabis?

You beat me to it...twice a week!
I had identical hopper damage last year, I watched the spots spread, took weeks.
It might be septoria or something else, in the veins rather than surface. They spread whatever they pick up along the way.
Point is, hopper damage isn't just the initial bites, they can allow a pathogen to spread as well.

Go where? I asked a simple question. If you use Daconil that's up to you. I wouldn't myself but if you're comfortable using it on your plants then continue doing what you do.
