Lots Of Yellowing Leaves Burnt Tips Yellow Veins

Looks kind of like early blight. Could be fungal.

Crap you might be right. There has been other plants in my garden and around the yard that have been geting weird burning I thought from heat. I took some photos of some of the other plants in my garden. Let me know what you think. I have never seen or had to deal with blight. I will go get some more pics of my mj leaves

If that's what it is I would cut off all the infected leaves so it doesn't continue to spread. Put down some compost to cover the spores. Treat with this 100% cold pressed neem oil. They make specific fungal sprays but I don't particularly like them.https://www.amazon.com/gp/aw/d/B00AWQWWS0/ref=yo_ii_img?ie=UTF8&psc=1

FYI you do not want to use that neem oil during flower. You might try real compost tea. I have heard that the bacteria will fight it off.

Here's a few leaves off my mj plants....

@Seamaiden is there anyone that is blight specialist that can share some insight/comformation on these before I go spraying with baking soda, oil, and soap

I am going to be talking out of my ass at this point. It is almost impossible to diagnose by looking at a leaf you really have to know the history of your plant and what you are feeding how much sunlight watering schedule everything about it to make the right call. I will take a guess and say those came out of the plants that were in the pots and the pots are drying up just a little bit too much in between waterings and you might need to add sulfur. Once again talking out my ass at this point.

 

[dnewsome2]

Not talking out my ass I can tell you that real compost tea works like magic LOL.

 

[dnewsome2]

Here is some good info I found. I bet there is more out there if you do enough research.https://www.google.com/amp/s/www.dinafem.org/en/blog/common-fungi-attack-marijuana-plant/amp/

I don't think the mj has blight. I'm gonna try watering every day and see if that helps also gonna foliage feed with some ph compost tea. Still trying to figure this one out lol

Not sure if you meant that for the OP or my photos.
Nice idea man. I'll have to try that. I thought possibly a root issue as well. Tried some vaseline around the base of a stem but didn't see anything.
Some of them yes but not all. Some still have substantial strength even when pinching the stem to pull off.
My current thought ( just posted in my grow diary) is a K lock out from the water softener on my well. I was doing some reading on that and it has had the most symptoms match up. I'm doing a flush with a clearing agent and ph'd water and will be watering from a bypass of the softener from now on.

Hoping @mauiinfinity is having some success.

Nice RunTheJewls avatar, btw

I know of a guy that had high nitrate levels in his well water. Worth an analysis.

Yes I was wondering if sulfur would help.

 

[Organikz]

Definitely. Calcium sulfate or gypsum is great for keeping magnesium from building up and compacting soil. I only use calcite lime. If you add dolomite lime to your mix you've more than likely filled the soil with magnesium. From an organic stand point i would say he's messing with it too much. We have a saying...less is more.

Thanks. we haven't had a complete test done. Just one that did the basic comp. Unfortunately the tests here are stupid expensive. I know its worth it but hard to justify at times. (we don't use our well water to drink due to high sulfur content. Just laundry and bathrooms)

Did you say earlier you were running it through a water softener? is this water softener the kind you add salt to or is it an Ro?

Yeah mine is a brine type system. That's why I am trying a flush with a clearing agent.
I don't think the OP has a softener but I know he is on well water.

Ok my bad

no worries. Better that you ask so people don't confuse my comments or pics for his. I don't want to high jack his thread. He was just having a lot of similar issues that I had been having for a couple weeks.
I'm trying to gain any insight I can. The big difference from last year to this year for me is having the softener.

 

[Organikz]

It's still hard but I basically ignore any deficiency for the first month. I know the soil has what it needs. People should understand a plant goes through an acclimation. If you transplant any flowering bush it doesn't flower for at least a year. Once you start chasing a deficiency youre doing more harm.

My mom was a horticulturist. "First year to grow. Second year to show."

My tomato plants were like that for years, and it was from dirty cages (I think). I kept transferring the blight, year after year to the plants. I got new cages and moved the plants to an uncontaminated area and it stopped. But it looks like a blight.

Did I get it?

*Edit*- @mauiinfinity I thought you knew the answer! lol. I thought this was a "test your knowledge" type of thing.

So, it looks like a typical blight to me. And you have several other plants around with it. I would get new cages, wash the dickens out of those pots, and relocate the plants next year if possible. For now, if it is blight, not much you can do.

Do cannabis plants get blight? I don't know, I don't grow it outside. If so, I'd say that's what it is.

If it's not, it's doing an amazing job mimicking it. Also if it's blight, over watering won't help.

I just grabbed a pic for you of one of my tomato plants. Leaves shrivel like over watering. They turn yellow and often browning starts at the outer edges working it's way in.

If you figure it out for certain, I'd like to know.
