But let me describe conditions so that you can assess the situation better. Iwill also provide a link to another site where we discuss the disease in depth and you can see multiple pics of its affect.
When a plant is nute deficient there is a pattern of yellowing: the largest and lowest leaves will yellow and fall first if nutrients arent supplied and then systematically those larger leaves will yellow futher up the plant. If the condition persist, the lowest secondary leaves will yellow and then move up the plant from the bottom.
With a fungal disease such as blight, leaves that have the fungus spot up,yellow and die first regaudless of their location on the plant. Not necessarily from the bottom up but instead, can yellow randomly on the plant. Lower leaves do often yellow but after that yellowing is random and not the systematic yellowing seen with nute deficiencies. I see lower leaves yelllowed on your plants but i also see some smaller foilage thats yellowed and some that is higher on the plant and out of sync with nutrient deficiencies.
If its the blight, the plants will defoliate and even die over the next several weeks. Even if they survive, the yeild is devestated.
Ill go to the link and post it.

Ive used the immunox for 2 years now. As long as you have a 30 day lag between last spray and harvest, there is no residue, taste or problems. Here is the method ive come to use and have found it crop savingly effective.
I use 2ozs per gallon and treat all plants late June. I apply a 2nd dose in early july, about 12 days after the first dose. I then apply a 3rd application at the end of july, aug 1. These 3 doses have a cumulitive effect and protect the plants until late august while at the same time, it creates nearly a 60 day lag time between last spray and harvest.
If i have any fear of the disease in aug/sept, i may apply a application of Daconil. its a contact and not a systemic. It only requires a 14 day lag time but if applied mid tolate august, its 3o days til oct 1 and thats plenty of time for it to wash off.
Ive used these products and their safe when used properly

Hey Clodhopper, Good deal. I'm heading to home depot and they have some immunox products, but not sure which ones to get. Can you be more specific? There are a bunch of different types. Thanks man.

If your watering everyday you could dry letting it dry out some than flood it so all your soil gets saturated,if theres dry and wet pockets in your soil it can cause nute lock or so ive read try researching dry/wet cycles,its good to let it dry out every so often,i dont think its the size of your pot ive grew plant that size in way smaller pots without issue besides smaller yeild.
In the past I've watered pretty regularly but my buddy told me to stop watering soo much. Before 2 days ago, I hadn't watered in like 3 weeks. Of course the rain didn't stop falling until a week prior to me using the copper sulfide. Seems like th plants really liked my watering them and I added some Earth Juice micronute with the copper when I sprayed. The plants look ok now, but it's only been a couple days. That's why I'm really wondering if I should spray them down again tonight with the Ortho Max stuff I just bought. Gotta read up a little more on it.

FINALLY! Found some Spectracide Immunox® Multi-Purpose Fungicide Spray Concentrate at Lowes. If this shit works as well as everyone says, why doesn't everyone carry it?
Still losing some leaves on the plants. Only been a week, but figured I should have been able to stop the plants from losing their leaves by now. Liquid Copper, Chlorothalonil, and now this Immunox stuff will be the last stuff I try. It's been raining off and on for 4 days now. Put another light dose of Liquid Copper on last night even though I knew it might rain overnight. Woke up this morning with a downpoor again . Now I get to go out and reapply. This shit is getting expensive. Think I may wait until the rain is supposed to quit then go spray with the Immunox. I hate this shit. Now that I know what I have, next year I plan on dosing them the first week after transplanting my babies into the garden. Then every couple weeks thereafter. I can't afford to go through this shit again.

this blight is in the soil I wonder if I could drench the soil around my plants with Immunox?
I've been spraying the top of my soil as well as the plants, but i'm not sure if it is helping or hurting. I haven't put on the immunox yet, but i will when it stops raining. Supposed to rain for another 4 days. Good luck Smoker. Definitely starting early next year, long before I see it.
