Probably.
Might be a different term?
Im not sure.
All the roses get black spot here, come autumn.
But i havnt had it with dope here. Might be climate related. Mildew always seems to make a home first.
You might ne right according to Royal Queen Seeds on a Google search. Seems to be termed "Yellow Spot".
Maybe Black Spot is the same disease. Just a different variety?
Im gonna have to do some reading.
Thanks mate
Upon reading, "Diplocarpon Rosae" is the black spot fungus. It does seem to be two different things.You might ne right according to Royal Queen Seeds on a Google search. Seems to be termed "Yellow Spot".

Leaf Septoria's really starting to interest me.
I'll keep checking in to your thread, to look for updates.
Cheers.
So I tent to have pretty “ghetto” set up going and ive realized the humidity in my setup has never reached over 60% which is like the minimum you want for veg... in averaging around 45%humitity. I know thats not a good thing but the lower the humidity the lower the chances of it being a disease or fungus would be low then?
Yep.
Its always so much more likely to be environment, before disease.
Even if it was disease, its likely the environment that caused it.
Think of environment as your plants immune system. Keeping the environment in check, aids the plant to build its own natural resistances to pests and diseases.
One example is a low ph in your soil. You get an abundance of anaerobic bacteria. Creates an anaerobic root zone. Anaerobic bacteria starts feeding on the root tissue. Roots start to rot. Then bugs like fungus gnats get attracted, like flies to a steaming fresh pile of shit.
The very first thing to do. ALWAYS. Is make sure your environment is optimum. Even if you know its disease, and you're about to spray.
Optimal environment is a plants first form of defence. Probably a good analogy, is to compare it to a firewall on your pc.

For Tim & op, this is leaf septoria AKA brown spot, it starts in one tiny brown necrotic spot where the fungus takes hold if conditions allow, this is running through most of the plant already
Remo chemo is not a great plant to run if you're in a humid environment, (cheese is another that wouldn't do well here in this time of year) this plant is as good as dead when I wake up and have coffee, no room for weak plants in my garden
..of course I've also got a cloner full of cuttings of it :-/ and another still in veg to toss so that'll free up some room if nothing else..
Today will put the air conditioner in and seal the room, the plants will still be culled I do not want sick around the healthy plants
a plant with even the level of septoria you see in the picture will not thrive, but will cause more stress and problems by trying to keep it growing.

That looks like calcium def to me. Leaf tissue analysis on multiple strains of cannabis show calcium being the biggest % of makeup. Almost as much as NPK combined on many of the strains .
Could it be possible you are using hard water?
Maybe that is why your calcium treatment didn't work?
Were you trying to fix it with carbonates? calmag?
Another thing to consider would be nutrient interaction and whether the calcium is being antagonized by too much of another nutrient. Doesn't appear that way to me but something to consider especially if you are high in magnesium.

I also chased it thinking it was this and that first at first, Cal than mag then nothing helped and plants with dropping dead everywhere then I got my humidity in check and it all stopped
nothing us lacking, just never had to seal the room this early not even close but it's been nothing but rain and cold in New England particularly on the coast so looks like an early start :-/
.. here's another picture, classic septoria (early)
Waters 104 PPM I'm using GH floral Trio in ffof, supplement with light calcium, than magnesium on a fairly regular basis, if not every feeding. Sealing room today, may keep that plant around not sure yet, not finished trimming it
* the white specks all over it is baking soda spray

I have a grow journal on the Remo-Chemo, there's a link right above in this thread, going to keep the plant alive and going to transfer everything about septoria and that particular plant to that journal as an experiment ?
I'm going to supplement it right now with some gh cal-mag gh and we'll see how it's going to go ? (although I already have a pretty good idea I'll save my thoughts for my grow journal and get out of Op's thread) drop by and check it out!
-good luck!

that does not look like leafspot[blackspot] that I get on my outdoor girls it does not show up on the eastcoast till mid aug it overwinters in the ground but doesn't bloom till mid aug, when we get fog an warm nights, an as long as caught early a simple copper fungicide will get most plants to the end fine its not the end of the world.u sure your in newengland cold an rain??its been a very dry warm spring in my part of the newengland we r on the edge of drought no rain here in almost a month

yeah ive gone years on these forums trying to figure out if its cal/mag deficiencies/ph problems etc..Its now in all my outdoor spots..Its defastating..ive seen a plant be killled by it within 2 weeks. Cooper slows it only..once theyve got it...its over . Yield down to about a 1/4 of what it should be
