Cymbidium seedling leaf tips turning brown
I was in the greenhouse today and noticed that 30 of my cymbidium seedlings, all the same cross, all have browning leaf tips. Could this be fungal? I want to stop it before it kills all my babies.. None of the other seedlings in my greenhouse are exhibiting this browning. The leaves are not dry and the mix is damp but not really wet. Do I need to cut the bad parts off all 30 plants.. if so is there an efficient way to do this and still stay sterile?
