Hello all! I would like to start a thread regarding Mold, Fungus, Blight and Mildew! We can all find info on powdery mildew but it seems to be a little hard to diagonse other mold, fungus and mildews. With that said i think i have a leaf spot fungus.

Im looking for a little help...Im confused as to the problem/s below. Ive been growing for awhile and have recently ran into some problems. I have been an organic (amended supersoil & compost tea) guy now switching to Jack Duo. Anyway, have been having trouble cloning lately in my DIY aero cloner, slime on stalk, dying before they can root, used to be 100% last pull was 50%. These last clones rooted and have only got Act teas. My fear is a leaf spot fungus, mold or blight, tho they could just be hungry for some food and be deficient. I will be hitting the with Jacks Classic 20-20-20 but any of you thoughts would be helpful. hope the pics project what im seeing. small black dots. and issues on the edge on the fan leaves. Please help, ive been reading all over and I do think it is a fungal issue maybe resulting from bad original rooting and a wet media. Thank you in advance for your input!

It would be nice to build a decent list of preventative solutions and products that help fight airborne pathogens. As i obviously need a better disease prevention program and bug for that matter. An once of prevention is worth a pound of cure!

If u think its a fungi issue, try using actinovate. Do the soil drench application. Whenever I start getting those leaf spots, I immediately start making sure my ph is in check.

Thanks Mongo! I will look into Actinovate. I sprayed them down with Serenade and will be adding some cal mag. A buddy of mine thinks it has more to do with deficiency. And if it is mold/fungus it developed because they are weak resulting from the deficiency. Ph seems to be pretty steady at 6.5.

AAHH! This shit is getting worse.. So the plants that i recently put in flower, which i had treated with Serenade are showing signs of yellowing, some on the bottom and some in the upper canopy. They also show wilt, though it doesn't seem to be over water or under water. Ph might be a little low. Some of my fan leaves looks like something ate them, parts just gone! I did identify the bugs, or at least the ones that i looked at under the mic were gnats. When i looked at some of the leaves under the microscope i noticed little white bumps, not trics but looked similar though this plant is in veg. Help. I need to figure out the best action plan! And the cuttings that i took are showing similar brown patches in the heat dome. Please give me some insight....im down and out right now.DSC_0001_01.jpgDSC_0001_02.jpgDSC_0001_03.jpgDSC_0002_02.jpgDSC_0002_03.jpgDSC_0003.jpgDSC_0003_01.jpgDSC_0003_02.jpgDSC_0004.jpgDSC_0004_01.jpgDSC_0004_02.jpgDSC_0005.jpgDSC_0005_01.jpgDSC_0005_02.jpgDSC_0006.jpgDSC_0006_01.jpgDSC_0006_02.jpgDSC_0007_01.jpgDSC_0007_02.jpgDSC_0008_01.jpgDSC_0008_02.jpgDSC_0009_02.jpg

This is a very sad day, ANY advice is appreciated. I fear that this is Leaf Septoria!!! I hope not but have to think for the worst and hope for the best. Will sulfur burn work with a Fungus like that? This issue has been getting the best of me for a few weeks now. Im not sure what me next move should be. Thanks friends

So i dont think that it is a fungal issue...the plants are looking much better overall. Though there are still a few issues present. Not sure if this is a nute issue or ph issue. Ive only noticed a few fungus gnats which i will be treating with mosquito dunks. and ive inspected the leaves with a scope and didnt see any bugs that would be causing these problems. Let me know if you have any thoughts.

thanks

Just want to report that I had the exact same leaf phylotaxis that you have (brown necrosis, combined with that wrinkly pocking and poor development) after leaving clones in the dome too long (took FOREVER to root because of cold temps). I feel that this problem is fungal, from constantly high humidity for around a month.

Now that they have been transplanted, my plants are starting to grow out of it. If I keep humidity low, new growth seems to outpace this infection.

Thanks Kind Time! My humidity is low in my clone room so hopfully they will bounce back. I also think that the plant i took cut from had a bad mix of soil, as well as, a few bad waterings. The original clones in this post took a little bit to start growing but now they look much better, though lacking some Mag and Cal....Did you treat with anything?
