I have now had at least a dozen seedlings, all peppers or tomatoes, bite the dust while still under the lights indoors. This has not happened to me in many years.
I don't think it is damping off. They don't bend over or lie flat and they don't have any browning or pinching in at the base of the stem. I haven't seen any sign of fungus gnats and I always do the cinnamon water. The little seedlings just sit there upright, where they are and yellow and shrivel. But when I pull them, the little plants have ZERO roots left. It is spreading. Two more just bit the dust and one of them was one that had all ready been potted up into four inch pot.
All of them had been transplanted at least once, so I know that at the time of transplant, they had good healthy root systems; I cull any that don't.
I sifted through the soil left behind where some of them died. I could not see anything. So if this is some kind of insect / larva eating the roots, it is very small and difficult to spot. I guess the other alternative is some kind of fungal disease that the cinnamon does not work against.
Any ideas? I will be so bummed if this keeps spreading through my plants....
