Looks to me like LSF (leaf spot fungus). Probably more commonly known as rust. It is a fungus that attacks older growth first, but can quickly progress, and if not treated can kill your crop eventually. There are many treatments for these fungus attacks. Chemical and organic. I would go with an organic option first. A sulfer burner would almost definitely kill it but they are stinky and cost a bit more than a spray. Organics: there's "green cure" which gets mixed reviews. I used it with success on powder mildew outdoors. A citric acid based spray is probably what you want. I'd try these before going to a straight chemical. (DO NOT USE EAGLE 20!)

Was looking at “green cure” on amazon and it looked good. Will order it today and get it in 2 days... unless you recommend something else I can get off a shelf at Walmart/Lowe’s/Home Depot.

Baking soda works well too (but copper is the best) you'll have to search the baking soda / water ratio though, I have it mixed by the gallon and I can't remember what I mixed it at?
I think it's a tablespoon per gallon but TBH I'm going to have to look it up too when I run out of this jug
I spray neem oil every plant every Wednesday whether it's showing septoria or not as a preventative but do not spray neem oil on flowering plants much past 2 or 3 weeks of flower, good luck!
* I can also recommend a sulfa burner that I'm using with good results if you decide to go that route let me know

So I can use just water and baking soda? It’s 2 weeks into flower so I’d rather not use neem oil.

.. it's this let me know if you have any other questions I got it on Amazon it's about 78 bucks if I recall
I can't exactly tell you what to use I use everything mentioned and I'm looking at milk spray soon too, so I guess I'm trying to say try everything but right now you can mix up baking soda and treat your plants asap!
.. make sure you spray underneath the leaves just look up the recipe first cuz I can't remember if it's a tablespoon per gallon or not[/QUOTE]

Big dehumidifiers your best bet I don't have the five or six hundred extra Watts available often so I use sprays and sulfur, goes away half the year comes back in the spring be gone in another month, but it's a nightmare. The coppers your best bet
Lowe's sells it in a premix but you might want to consider the concentrate for Value because you're going to be spraying a lot of it

Looks like a lot lol I’ll have to read up more on that sulfur burner. Seems like a lot gs using copper and just spraying on?

It's just copper, says you can use it on Tobacco or fruit up to the day you harvest, I do Bud wash when I harvest anyway, so..
Just don't use neem oil once it starts stacking or you'll be throwing all the bud in the hash bucket it tastes terrible and looks nasty too
The trick is to use one treatment or another every 2 or 3 days depending what your plant requires not so much any one thing or the other in my opinion
copper is the best one if just choosing one but baking soda is there right now and it's good too

Yeah, I told ya the sulfer burner was alot to deal with. Green Cure is 100% organic I have never used it for rust tho. However it works well for powder mildew. That's what I used it for. If you you do use it go with the lower end of the recommended dose, because it will burn at higher dose. I have heard citric acid based fungicide works well for rust. Bet you could do a quick Google search, and find home remedies for rust fungus. Maybe do that first.

That's why I mentioned baking soda because most benign. I've heard someone who I hold in high regard as a grower recommending the green cure so it's probably fine too ? But I've only told you what I do and it works too good luck

Sorry didn't see this post yes you can use this I think it's a tablespoon per gallon? you're going to have to look it up cuz I don't know, I mixed two gallon jugs of everything and they last a while
Be prepared for all infected leaves to die; in fact I haven't told you yet but you're going to need to pull all infected leaves off, sorry
they'll be dead in a day or two anyway but the idea is to remove as many spores as possible from the garden area
you're going to need to start spraying walls with the copper fungicide or something similar and or burning sulfur
I can barely control it with everything I'm doing to be honest

I’ll try baking soda first as it seems to be cheapest/I already have it in my kitchen. If it doesn’t do much I’ll try copper spray next.

Sulfur's the easiest; plug it in, shut the door. Initial cost is the highest tho. Good call on the Eagle 20!

I lied... I don’t have baking soda. I thought I did. Well if I’m spending money now I’m just going to go with copper spray. Ordering the concrete off amazon but also going to Lowe’s today to see if they have that mix. So I can use it now and not wait 2-3 days.
