Leaf septoria

[dwig]

pretty sure I have a case of leaf septoria... Plants are kinda small and I need to flower them end at the end of next week. Just my bottom leaves have this but ive lost a set already. Can someone confirm this and give me some suggestions?

Grow info :
Lights
Temps
Medium
Nutes
Water
Ph
Light cycle
Strain

Boxers or briefs

Most important ......... Take pics in normal light.

Disease is pretty unlikely before a ph or nutrient issue.

Tbh.
It looks like lockout, to me.
Calcium looks deficient. Deficiencies usually start from the bottom fan leaves.
Looks over watered too, judging by the wrinkle and general sagg.

Im going with over watered, and overfed. Probably ph too low as well.

Need some info.
Medium?
NPK% total? (give your calcium and magnesium total too)
Ph of your root zone?
Ph of your water, and feed?
Ppms / ec?
Water source? (tap, ro, well, tank etc)

Im growing with advanced nutrients connoisseur and I have calimagic but havent used because i read after soil should have enough mag and cal in it. You can look up my soil (Berger BM6 HP).
Plants were over watered a couple weeks ago even after several dry outs before light waters they never took back shape. Also water source is from the big jugs you get a water depot until I get a rain barrel so my starting ppm is around 5 when i test.

1200watt mezhi led high temps are 83 lowest was 67. Medium is Berger Bm6 Hp soil and nutes are advanced nutrients connoisseur. Ph of water when feeding is 6.5-7 i aim for 6.5. Im also running purple kush and its under a 20/4 cycle right now. Have some auto seedlings with them.

Ok.
Nothing added yet? Just soil and water?
Whats your soil's ph?
Whats the volume of your pot?
Whats the volume of water, you feed?
How often are you watering?
How much waste runoff comes through the pot?
Any feedings of anvanced nutrients at all?
If so what dosage, and how many times?

No im watering wither the connoisseur at 250ppm now (ive done this twice with fert weeks before i wasnt using any). Before I would wait till near bone dry then do a heavy watering but it awalys take so long to dry and I would get over water symptoms. Now I just water little bit when it gets dry just enough so i get no run off or until a few drops come out the bottom.... Its the only way I dont get over water symptoms. Room isnt cold ir anythig either. Lights run at 20/4 and the hottest was 83 and when lights are on it averages around 80 by the plants and when they are off it will usually stay around 70 but sometimes drops to high 60’s.

Ok cool.
I think not drying out fast enough probably started the problem. Wet roots start to rot. Then water uptake slows. Ph can start to fall as well, because more organic matter is decomposing. (need better drainage)
Sounds like you're underwatering too. You do really need runoff each time. Otherwise it does start to get salty, from nutrient and decomposing matter.
Id be tempted to give them a really big drink of water, once nice and dry, and get some good runoff.
Aeration and drainage really seems to be the cause tbh.
Honestly id get that soil sample, and test the ph too, for peace of mind.

I'll upload a few pics, and links which may help you confirm the diagnosis.
Give me a few.

Calcium deficient leaves-



Hope it helps mate


Imho check soil ph first off.
Then I'd be drying the pot right out.
Then big drink of plain water, until good runoff.
No more nutrients, until the roots are filling more of the pot.

Better drainage next time. I see there's perlite. But perlite is only good for aeration.
You need some sand, coarse river sand, gravel etc.
Even a layer of gravel at the bottom of the pot.
Otherwise I really like the air pruning pots, if you don't use them already. Drain well. They dry much faster too. Great for indoors.

cant see anything with the purple light on take a pic under natural light

Over two nasty seasons I fought and finally beat septoria! ..so if you can get some natural light pictures up I can probably see if it is or isn't, and make a suggestion or two how to defeat it ?

A whole plant shot in natural light would be best and maybe close up of a couple of affected leaves

 

[Beachwalker]

Anyway if it's septoria the answer is you have to control the environments humidity.

.. there's no alternative, that's why it took me two seasons cuz the second season I thought I could beat it with a handful of sprays, a sulfur burner forget about it

I tried it all. you got to control your environment! ..for me it's August -September when it strikes here, but not the last year, and not again!

Short of full environmental control a sulfur burner used regularly will give fair results, also add many fans (Vortex / High Velocity type)
-good luck!

Cannabis eats calcium and magnesium in high amounts. I see calcium and the start of mag def in your pictures.

I get it most yrs on my outdoor stuff simple copper fungicide takes care of it,u just gotta catch it early,never seen it indoor room would have to be pretty swampy,i bet it isn't black spot I have lost whole plots to it before I knew what it was,now I see it every where I look

 

[Beachwalker]

Yeah my humidity during dark was out of control, plus the weather last few years has been just right for mold, fungus and all that, cool and damp

I tore my whole garden down the second season, lost all mothers too :-/

ya nasty shit it doesn't kill the plant just fucks it up,all my outdoor stuff get sprayed with copper no matter what,tomatos an roses r big vectors

 

[Beachwalker]

No doesn't kill it but it leaves so little of the plant behind that it's not worth it plus they look so freaking Dreadful I couldn't stand looking at em anymore so many dead leaves so fast devastating you got to control the humidity particularly if you're in humid area I'm on the coast of New England and it's a fucking nightmare here believe me I think you are in New England too cold and damp and rainy last few years including this spring's terrible I'm almost glad I'm not growing outdoors (but my electricity bill isn't so glad)

light depo is the way to go up here,only reason I do 12 full term in greenhouse is its legalLOL last yr was bad worse I seen in long time

This is also what septoria looks like. the way to figure out which it is, from my experience with it, is when you treat for Cal and/or mag, if it doesn't respond, but gets progressively worse it's time to consider septoria ?

I have to admit i havnt had any experience with septoria myself.
Im not sure it grows where i am locally.
Plenty of black spot, mildew, grey mold etc.
Septoria sounds nasty man.
