Hi gurus having a big problem with a disease or pest I’m not sure ? Thought it might have been broad mites (never had before only spider mites)but have sprayed hard over two weeks and no change never seen anything like it in 20 years of growing. It has wrecked two runs now . Any suggestions what it could be. Medium is quality coco not reused . Using good nutrient as well
Cheers for any help paddy
I just looked at the pics and I would be checking for bugs. I can see some on the last pic just on the top, or at least some bug shit. You might want to look under the leaves, or maybe you don't, lol.
I don't use coco, but if I did I'd probably do a H2O2 drench.
And when you say good nutrients, what does that mean?
