Browning leaves, mutating - tearing new veg
I am doing my first run in living soil, using nothing other than airated tap water under 600w kind led's which are 4ft from canopy. I am growing karma genetics - headbanger, biker kush and old dirty biker from seed and they are currently about 4 weeks old. My temps are between 19 and 26, humidity about 60%. Around 2 weeks ago the tips of my leaves started to brown so I raised my lights a little as they are quite intense which seemed to help with the browning but then the new growth started to mutate. At first not so bad but by now it looks like it has been torn up, big gashes in some leaves and it almost looks like it's tried to top itself. The lower parts seem ok and it seemed to start with the old dirty bikers which are at the farthest point in the room, but is now affecting others. I have predatory mites on the go and am giving a foliar spray twice a week with karanja oil and dr bronners. I am absuletely stumped as to what is causing this as is all the other growers I know, we've never seen anything like it! Anyways il attach some photos of the madness and hope someone has some knowledge of it ....
