Hello everyone, I was ready to transition my plants into the flowering stage, but I realized that what I thought were just watermarks or signs of overfeeding or underfeeding might actually be a disease. As far as I can tell, there are no pests; I believe it’s a fungus.
I checked online, and I think the little brown spots could be something called Septoria.
Please note, there were many leaves with little brown spots, particularly one plant—but I picked them off yesterday, so the ones I can show now don’t have too many spots.
In any case, there is something more going on than Septoria.
Take a look at the variety of problems on those leaves…
I bought some Canna Cure and sprayed it today.
I think the problem developed in the veggie room when i had a 85% RH and high temperature, happened a few time, the tents walls were wet with condensation. I put a fan now.
Sry my phone went crazy, the spots on the leaves if you take your finger do the rub off or smear or anything at all. And ppm,pH numbers is you have any.
Hello, thank you for your help.
they were on vegetative stage, i was only giving them a light nutrient designed for the vegetative stage, i have kept them like that for about 2 months because i needed to wait for the other to finish flowering.
Ill check now the brown spot as you told me
Sorry, I also meant to say I have not ppm because I’ve not started to give them base nutrients,
I don’t have too many leaves now with those little brown spots, as I mentioned I took them all off yesterday, but the one I have I passed my finger and nothing changed, no changes on the spots
I just harvested my first crop, i used a bottom feed system, but I had good results, i am using the Sensi coco line and I thought I didn’t need to add cal mag
That does appear to be a bit of septoria in your pics.
If buds haven’t started to show yet then you can spray with a fungicide to get it under control.
I use safers Defender if I have issues.
I really think amongst other issues there is a disease there, the brown spots spread from one plant to the other, I left it a bit too long because at first I thought it was a minor problem
If it was a fungus or mold or something like that I’m pretty sure it would have a residue that when wiped or agitated would transfer to your finger or see particles floating around.
I very well could be wrong .just brainstorming with you to try an help
@ACMilan The reason for not using in flower is the sulphur in it.
Will make the buds taste like an unburnt match smells.
And @DanB The only one I’ve seen wipe off with your finger is white powdery mildew.
Septoria is a different animal and causes the necrosis in the leaves like in the original pics.
it doesn’t say fungicide
