What the.... is going on with my plants?!

[disboikrazy]

Not sure what’s going on what my plants. While entering flowering stage this problem arise! Now it almost destrying my plants! Any ideas as to what’s going on? Is it lacking nitrogen? Overwatering?
I think it’s leaf septoria and foilar spray them with some Dr earth fungicide last week but this week they’re going downhill fast! Help fam!

probably over watering...

 

[OG_NoMan]

Leave spot disease looks similar IMO, good luck.

 

[disboikrazy]

I’m pretty sure it some spot disease that is on the leaf but not sure how to treat it.
There’s like 100 acres of corn field near me, do you think it some kind of fertilizers that they are using that may causes this?

 

[CrushnYuba]

I don't know anything about spot diseases... Have/what have you babe feeding them?
They look burnt. Like you gave them something with to much urea or something in them. And then maybe they dried out to much

The plants do look over watered, but the leaves do also look like they have something. They may be seperate problems, or not. It's common with cannabis because it's tough and doesn't usually show damage from the first thing we fuk up. By the time symptoms show we often have more than one thing to solve.

I would start by opening up the plants by bending the branches outwards to let more air and light in. That will also make them transpire more and use up the excess water.

I used Jacks Classic 20/20/20 with jack bloom blister 10/30/20. Not sure if it’s my nute or what, cause I do keep the ppm under 1000 and ph 6.8-7.1 based on my blue lab combo. Could be that I’m on hard well water which is around 250 ppm. Might be because of the water softener too I’m thinking.
I just Delayed my watering timer for 2 days before next watering to dry them out a bit.

I’m stressed the after out cuz after all this time and effort my plants is fuck n I not really sure what going on with them.

Welcome to growing, I had to throw 7 lbs in the woods last year due to mold, caterpillars, and boytrytis. Learn from your mistakes and take your knowledge to the next grow

did you spray during the day when the sun was out?

 

[Teddybrae]

After looking at yr photos and the suggestions above I think watering on a hot day is the cause. If you watered with hose ... was the water in the hose hot from lying in the sun?

You should never spray anything on flowering plants.

I killed a beautiful autoflowering plant by spraying baking soda on it, to deal with mildew. Killed it in one day.

One test you can do is stand above the plant and smell the flower. If it smells mildewy, the plant is gone.

Think it's a couple things you got going on but i really think some of that is burn. What kind of containers are they in? It looks like a buried smart pot. Jacks and fertilizers like it are real hard to use in big containers/ in ground, and real hard to use outside.
You get an extra hot sunny day and they take up more nutrient solution then usual. It's compounded if out builds up. Big containers are hard to flush.

I used softened water the first time I ever tried to grow.

It killed my seedlings, and those few that survived were sickly and lived a sad existence.

It could have been that my pH was really acidic after softening.

I spray them this past Saturday with dr earth fungicide right before night fall.
As far as foilar spray, I’ve only done it twice this season and the last one being couple weeks ago.

Could some roundup sprayed on the corn field drift over to your garden? That would suck!

 

[disboikrazy]

Got them in 50, 65, & 100 pots with an timer watering system drip emitters that I rigged up. I set my watering to water at 9am and feed them 3-8 gallons.

I’m not sure what they used on their corn field but from my observation they don’t seem to do nothing as fall as foilar spray. Hell I don’t even see them water the corn. Not sure how the corn even get that big without watering.

 

[disboikrazy]

Guess I’m gonna have to hold back on feeding them nute n feed them straight water for now to see what happen.

That's so not allot. It doesn't sound like they SHOULD be getting over watered. how established are the roots in those pots? They are smallish pots for outdoor, and i would think by now they would be at least approaching being root bound in those containers. If that's the case, it's Damn hard to over water them. Not with 3-8g.
How does the soil look at the end of a hot day? How do the plants look if you skip a day or 2? Do they wilt a little? And are you feeding through the drip or by hand? Do you hand flush with water? Those questions can rule out a few things.

That's burn and dead tissue. Not surewhat the dead tissue it's from. Possibly bugs.
If it were me, i would rule out nutrients first. I would hand flush with tap water. Get any salt build up out. Then i would feed them some organic ish liquid nutes or water soluble dry nutes.
