Does anyone have any idea what I can do? I stripped all leaves that had the marks on it a few days ago and now slowly it’s spread everywhere. I’m absolutely gutted it’s getting everywhere attacking all the leaves apart from the small ones by my buds. Is there anything I can do, I’m using a bran new iws system which I’m thinking will need to be binned after this disease as I imagine it will have infected everything.. help

I’ve been feeding cannacoco a and b at about 1,4 / 1,6 and just upped it to 1,8.
I added calmag at 1ml/1l about 3/4 days ago after giving it a flush

and rh around 40/56%

I’m growing under led 600w Zeus pros

Never had anything like this

It’s my first time using led. And I’ve never used calmag before, I’ve been adding it for about 4 days now and it’s not getting better
