Leaf septoria on my outdoor ladies.

[757Botanist]

Can anyone suggest a good fungicide for my girls. Just started noticing it. I’m just trying to make it to harvest which looks like early November. They look a bit pale. I’m not sure if I should add nitrogen or phosphate/potash

Could you provide a closer pic of affected leaves? Old fan leaves can die back in some weird ways sometimes. I've been fooled before. Septoria will show small black necrotic spots at the cent of the yellow circles. Cucubert Leaf Spot looks like septoria but has a rusty colored center. This time of year you will get some old leaves fade and die back when the plant decides its done with them. I notice that on one of the plants that the fading fan leaves have a distinct yellow tint. Looks kinda like a banana peel, right? She needs potassium. I suspect that the next time you feed those leaves will get a brilliant yellow. Kinda like they are glowing. I'm seeing some purplish on upper growth. A nitrogen bump wouldnt hurt either. Looks like they are hungry.

If you do need to treat them you could go the biological route with a bacterium called Bacillus Amyloliquifaciens (Bonide Revitalize) or a copper based fungicide. Some people use a H2O2 solution.

Agree with @RootFarmer, better pics are needed. There is definitely something going on in the second pic, maybe heat stress/watering issue, canoeing leaves?

I will definitely get more pics

Ok posting new pics now!

Here is plant A:

Solid growth but leaves started yellowing. I thought it was overwatering, so I stopped to let dry out but yellowing persisted so I switched over to TPS this flowering nutrient that has a lot of potassium and potash. It helped a little then the brown/yellow spots appeared. I’m freaking out bc they been growing since march and I feel like I’m sooo close.

Here is plant B. Same situation, started noticing the leaves canoeing and turning brown. I’ve been using flowering nutrients but reverted back to adding nitrogen. She’s a big ole indica and I don’t want to lose her. HELP!!!

Howdy buddy. Any insight would be great. I’m definitely thinking it’s the soil, the pot is so big I hope I’m not overwatering. Yeah they are right up front lol hoping they make it to November.
