Can anyone tell me what’s going on here with this spotting? Is it a disease or a deficiency? Quite a few leaves yellowing and dying as well
Outdoor
Mixed soil
Gold leaf fem
Organic nutrients
I know gold leaf require extra calmag from previous grows so just gave a huge dose to each plant
There’s also lots of purple in the stems
2nd week of flower
It has been very moist and humid here as well
Thanks in advance for any help
@PurpNGold74 @NugFlush anyone?
That’s bug damage
could be Leaf Septoria. Leaf septoria, also known as septoria leaf spot or yellow leaf spot, is a plant disease caused by a specific kind of fungus known as Septoria lycopersici.
This fungus usually overwinters on dead foliage or common garden weeds. Fungus spores can also spread onto equipment like garden stakes and netting, before germinating when conditions are right.
Leaf septoria can be an extremely damaging disease, greatly affecting the foliage and growth of a variety of plants, including tomatoes, parsley, and obviously cannabis.
As the name suggests, leaf septoria is characterized by yellow and brown spots forming on both the upper and lower sides of leaves. The spots tend to be circular with dark brown margins and tan or greyish centers. They usually measure between 1.5 to 6.5mm.
Leaf septoria usually affects plants just after they enter the flowering stage and usually forms on lower leaves first. As the disease develops it spreads its way upwards, quickly affecting multiple leaves all across the plant.
Affected leaves will usually turn slightly yellow, then brown, and eventually wither completely. Leaf septoria rarely spreads on to fruit, so it generally won’t affect cannabis flowers.
If left uncontrolled, the disease can destroy a lot of foliage. This ultimately creates a lot of stress for plants and stunts their growth as well as the size of their harvests. Leaf septoria is particularly prevalent in areas affected by extended periods of wet, humid conditions.
I’m gonna take back the bug damage and say @proudm is right. I knew I had seen this before but couldn’t put my finger on it looking at your pics.
Wow that was informative. Ok how do I get rid of it?
Here is a copy paste I got from a site I like I would link it but well you know
Sounds like I have my work cut out for me. Bloody hell I’ve had the worst climate this year to grow. Won’t stop raining. Won’t stop being humid. Just horrible
Conditions to grow in.
You can try a fungicide, but I doubt it will help. On the use of fungicide, I don’t use anything but organic as if you smoke or eat it, well… Are they all dead? They will look perfect one day then gone. Try to let the soil dry., here is a homemade recipe instead of a commercial product .
DIY Fungicides for the Garden Learning how to make your own fungicide gives you control of the ingredients, many of which are already in your home. Here are some of the more popular items for use in making fungicide for lawns and gardens: Mixing baking soda with water, about 4 teaspoons or 1 heaping tablespoon (20 mL) to 1 gallon (4 L) of water (Note: many resources recommend using potassium bicarbonate as a substitute for baking soda.). Dishwashing soap, without degreaser or bleach, is a popular ingredient for homemade plant fungicide. Cooking oils are often mixed into homemade plant fungicide to make them cling to leaves and stems. Pyrethrin leaves that come from the painted daisy flower are widely used in commercial fungicide for plants. Grow your own painted daisies and use the flowers as a fungicide for plants. Dry the flower heads, then grind them or soak overnight in 1/8 cup (29.5 mL) of alcohol. Mix with up to 4 gallons (15 L) of water and strain through cheesecloth. Bordeaux mixture for use during the dormant season can control some fungal and bacterial diseases. You can make your own Bordeaux mix with ground limestone and powdered copper sulfate. The most recommended strength for dormant application is 4-4-50. Mix four parts of each with 50 gallons (189 L) of water. If you need less, like for a gallon, reduce the recipe for this homemade plant fungicide to 6 1/2 to 8 teaspoons (32-39 mL) of the copper sulfate and 3 tablespoons (44 mL) limestone to 1 pint (.5 L) of water. Using Organic Fungicide Recipes Now that you’ve learned how to make your own fungicide, use it responsibly. The term organic leads some to believe that these mixtures are completely safe, which is untrue. Use all homemade fungicide for the lawn and garden carefully, especially around children and pets.
So, most important is cleaning anything with bleach or alcohol if you are reusing pots, pruning with scissors, when adding a new fertilizer or spray, use on a small area or one plant till you know how they react. I don’t use any fert., spray, etc. full strength and don’t over fertilize, only buy premium growing medium, it makes a difference.
DON’T GIVE UP!!!
Unfortunately it is common for Marijuana…and deadly!
There’s your culprit. Lol. I don’t grow outside much so thankfully I don’t have the issue of fungus and disease. I’m not saying for sure that it’s leaf septoria as @proudm suggested. But that’s just cuz I’m not 100 percent sure…not that I’m doubtimg @proudm. Cuz I a, pretty sure it is some type of fungus. I’d definitely investigate as he mentioned as well as all possible fungus issues with it being so wet and humid. My friend has dealt with it in the past as he grows outside more and in the Midwest USA it’s gets very hot and humid.
Yea this summer has been absurdly wet. Think this will be my last outdoor attempt for a while lol. The bloody humidity just wrecks so many plants my indoor babies are so much easier.
Thanks everyone for the help. Love yall
