I'm growing 11 different strains outdoors and only one got it bad but unfortunately I don't know which strain it is as I lost the tag.
It might be Power Kush by Dinafem as it is growing more like an alfganistan strain which is what this strain grows like. Its about 3 weeks in flower stage already which is well ahead of any others I have. The only other one that got slightly infected was right beside it and was my Lavender from Soma. This strain I know is very pest and disease resistant but since it was directly in the line with this other, the wind must have carried over the spores to this one. They are both doing much better now but I do have to keep on top on it as I would hate for this thing to carry through into flowering stage. What a nightmare that would be.
Wishing the best for any other growers having to deal with this.

Quick update, I visited the local hydro store and told the guy what's been happening and he said people have been reporting the same issue I am having lately. He said the pattern he is seeing is that this shows up 2-3 weeks into flowering and the plant usually overcomes it after the buds set. I am at day 24 so the pattern applies to me. We guessed that the transition into flower is a time of stress for the plant making it more vulnerable and the plant should be able to outgrow it later in flowering. The other thing he mentioned is that nobody has seen anything affect it's progress which is scary and I also have not found ANYTHING that seems to affect it.

I hope it follows the pattern and goes away soon while my plant still has some foliage left....

Also, I think my pineapple express is a little touchy, it tends to yellow very easily with any amount of stress but also grows vigorously when happy. Here's a pic of a PX outdoors...

The liquid copper seems to be working on it here Dorje13, although its taking 2 treatments.

hamstring, the plants look nice!. if you can just survive this shit to harvest it looks like youll have a good one. Doesnt white wdow get tall?. Theyre the tallest plant i have as well. I have to stand back to take a picture.

We're on the same page. A bit ago i looked closely at the disease you first posted and looked at my leaves. The diseases are different. Shortly after, i posted that there seems to be 3 different diseases here. No. 1 is the disease your plants have, although its only on 1 plant, its on lots of other plants and seems to be slowly fatal. No. 2 is a condition that in which the edge of the leaf looks like it touched something poison and an immediate round yellow spot forms on the edge of the leaf. Within days, the entire leaf is dead and brown. This disease(2) is deadly and wont allow the plant to survive for more than 2 weeks after its first seen. No. 3 is a condition in which the large leaves begin to yellow and they get small black spots on them. within days the leaf falls from the plant and many other leaves on the plant show different stages of the disease. This disease defoliates the entire plant and then the plant wilts and dies.

This combination is one reason ive had to use heavy weapons to fight with. The liquid copper seems to be killing all conditions, but its capacity to help the plant is clearly dependent upon how early in the disease you spray it on the plant. When applied early as soon as the disease is seen , there isnt hardly any damage to the plant, but a plant that is fully involved is helped and the disease is stopped but a toll has been taken, and while it recovers its been diminished .

Plant looks great I don’t see any signs of disease ???


Like DS said I think we are looking at a couple different phenos (for lack of a better term) of this disease because the shit I have doesn’t stop during budding. Grant you there is less sign but it attacks the small bud leaves causing bud rot. I guess my pics are deceiving because I'm not really sure I will get enough smoke to keep through the year I have really low expectations.

Hey DS glad the liquid copper is working I used Serenade this time because I had it.

I hit everything with a huge dose I hope it helps.

I too think we are looking at some differences in diseases but they could be similar. My pics are deceiving though I have one plot with some early finishers (two weeks from done) and its basically hash weed because the buds all have dead spots with small amounts of mold. If it stays dry i should be ok to make hash if it gets humid or rainy I'm fucked. I made hash once from extremely moldy weed because I saw a thread on how to do it but it still tasted like mold once done.

The GHS WW doest take kindly to this disease they shed leave by 10 and 20s. They just went into full flower.
I'm pretty sure you grew these before the branches don’t look too strong do they hold up well??
I am hoping to at least get some personal from this if they finish on time. I heard they start late but put on weight quickly and the indica pheno at my lat 42N they should be done by Oct 15th, which cuts it too close, but I never grew a white strain and had to try it. So much for stealth I actually would have toped them had I known besides not being stealthy they are hard to care for because of the size.

Good luck to ya this season.

It's one of my indoor plants that has it strangely enough... the od one is fine as far as I can tell.


I agree there are a lot of leaf spot diseases, but it seems like treatment is similar for most of them. I may try chlorothalonil, usually used to control septoria on tomatoes and I got some hydrogen peroxide.

I was just over at my "friends" place who gave me the infected plant from his veg, the disease is doing some serious damage over there as well. His veg garden, and possibly my flowering plant, are going to be a total loss unless we can figure out a way to stop it. It seems to be a lot more aggressive in his veg, infecting leaves near the top and bottom of plants indiscriminately.

Also... we used Eagle 20, a systemic fungicide used for PM, so that's another fungicide that doesn't seem to do anything.

Your killing me brother that sucks well the green cure didnt do much either. Shit I guess the liquid copper is the way to go. Thanks for the input.

Good luck on that site relocate stratmandu, but the same shit is everywhere i go!

Guys, i found the eagle 20 ineffective as well. A week later the plant i sprayed was nearly dead.

hamstring, how is the serenade working?

The liquid Copper clearly is effective. I tried to pick off any leaf that was significantly yellow before i sprayed the plants so that i could tell if more leaves yellowed. In every case, 1 week later there are only 3-4 new yellow leaves and they are really leaves that had some infection on them when i sprayed, but werent yellow yet. They continued to yellow. i have just applied a second treatment and i feel confident that it will end the scourge for me as it will be under control. Ive sustained damage to my crop because i didnt attack soon enough, but now i know. Every plant that just had a few yellow leaves in the beginning and didnt have the disease that bad yet, recovered well with no real damage to the plant nor any sign of the disease, so if its applied early, the plants arent damaged by the disease.

Now, the real question. I harvested a spindley/weak and terribly diseased biddy early that recieved the liquid copper treatement. Took it home, dunked it gently in water and then dried it out. I cant taste any chemical taste nor did it make me cough or gag. I think the stuff is ok. I dont think that i will have to apply any more after this last treatment and its still 5 weeks from full harvest so im hoping all will be well.
